  1. I picked this up to try more power with my H4s. However, I decided to get a 300B amp. The amp is as new and unmolested. (No upgrades) I ran it with EL34s biased, per Cary, at 50 ma. $2500, or the best reasonable offer plus shipping in the original Cary Double box. Pay Pal is fine. Feel free to PM me if you have any questions, or would like to speak on the phone. I misplaced the bias jack and assembled a new one. It's simply bell wire with a 1/4' jack with leads. The original EH tubes and a quad of EL34s are included.

    Hello dear Klipschers ,

     

    Just joined this forum after long search on the web. Recently purchased a showroom pair of Forte IV . My amp at home is a Yamaha as701 . After buying the speakers the amp upgrade urge hit me straight away. I read that the Yamahas and Klipsch get along pretty well so i was thinking of getting the Yamaha as3200 or maybe the as2200.

    I can get the as3200 here in Europe at cca 4400euro new. Would that be a solid combo or will i get a better integrated amp at that price range that works well with the Fortes ?

     

    Thanks !

    Vladi

     Be sure you can return whatever you buy/try.

    Do you think it's an aesthetic improvement or a sound improvement? I also used different speakers with contact bridges between bass and tweeter part of the xover. I have also experimented with cable jumpers and connectors that I soldered myself. I found the result not very impressive. After a bit of trial and error I came to the conclusion that a certain measure has the greatest effect on achieving a nice sound. I have to say that the jumper design of my speakers is a bit different from that of the Klipsch speakers. I have, as apparently usual with many British speakers, connections like the one in the picture below. The contact between the high and low circuit is made with a small rod that is then screwed in place. The contact to the amp is made via banana plugs. I have achieved an audible improvement by using a pair of pliers with a thin towel between the pliers and the knurled nut so as not to scratch anything. Then I very carefully give just a little force and screw the knurled nuts tighter with the combination pliers than it would be possible with my bare fingers. It is to be tightened carefully and with feeling. We don't want to overtighten and break anything, it's the touch of a twist. But the result is that I can no longer easily loosen the knurled nut without pliers with my bare fingers. The effect is less graininess, a more stable stage and a more pleasant sound overall. I would recommend trying it out even if it sounds crazy. But it costs nothing. It should be possible with the Heresey jumpers in a similar way.

    My thinking is that the in this way fixed nuts prevent micro-vibrations from being transmitted through the back of the speaker. Micro-vibrations remain possible if you tighten these jumpers with the force of your fingers only. I think this effect is much more decisive than the choice of a supposedly better material that costs more money but is also only metal like the original jumper. But as I said, just turn a little and with a lot of feeling.
    We would not have this problem if the jumpers were not there.

     The sound is cleaner and they are easy to install and get nice and snug. The Klipsch provided jumpers are not copper.

    Kind of an odd story:  Shortly after I had received LaScala during the family Christmas gathering at my house, I was demoing them in my room for my cousins.  Of course this required "medium loud" volume, but every time I would crank the volume past a certain point, one of my younger cousins about 8 or 9 years old would start screaming like he was possessed and refused to leave the room, thwarting my demo.  Tragically about 10 years later, it turned out he was possessed by demons....

    Great post!

    Hmm, should be grateful you had good sound at the concert, a little much to expect stereo in large hall, PA system.

     

    In the room, imaging is all illusion, elusive. Interesting when it improves, but I struggle to see anything beyond the strong center image, Left, Right, and center left, center right.  Depth is elusive, but sometimes one can hear the hall when audience applauds at end.  Yeah, most imaging is studio trickery, but can be entertaining.

     

    Even at the orchestra hall, live I don't see any image.

     

    Of course we all see differently....

    I see/hear like you and don't care about imaging at all.

    Yes.  Call it sour grapes if you want....  

     

    I hope I've been clear just my experience with a few transistor Class A amps ( Pioneer M22, Krell at the store ).

     

    Anxious to try a low powered SET amp on my Heresy.

    Inspire tube amps from Dennis Had are a great match with Heritage speakers. Do a search. 😉

    Thank you for the comprehensive information. This may sound as though I am greedy but with my sub turned on, I am really pleased. It is just if I turn the sub off, I feel like the heresy could do better, and my 50 watt amp is likely under powering..?? That being said, I would like to find the most synergistic upgrade for amplification. I did do the room crawl. As far as getting the phase right, I did it alone over the course of a few months LOL, a lot of trial and error but currently with the sub on, my set-up sounds fairly well blended on most music. The sub does not draw attention to itself on most music. The minute I turn the sub off, it is like what happened... Even the mids get thin.

     I have a room from audio hell. This may sound like heresy, but I think I will add a Schiit Loki Max to the rig.

    I’m a tube and Klipsch guy looking to upgrade. I’m tempted by Cornwall IV, but their size is probably prohibitive (I’m married 😊). Maybe a tube preamp, or a tube DAC, or roll tubes in integrated amplifier…? How to identify the weakest link? Thanks in advance!

     

    Equipment: Qobuz to ethernet PC Notebook with Audirvana or ethernet Blusound Node (2021) network streamer to Cambridge DacMagic 100 to Schiit Loki Mini+ EQ to Line Magnetic 210-IA 300B SET integrated amplifier to Klipsch Heresy III + Klipsch R-10SW.

     

    Music: 1920-1980 Jazz: Armstrong, be-bop, 1960-80 avant garde jazz. 1950-1980 rock: Classic rock, Zappa, Beefheart, punk, post-punk. Opera: Wagner, Puccini, R, Strauss Janacek, Bartok. Symphonic: Stravinsky, Bartok, Mahler, Dvorak. 1950-1980 Afro-beat, Jamaican, Brazilian

     

    The H4's are much better than the H3's. The tractrix mid horn makes a big difference and you will immediately notice it. H-4's and an upgraded sub will make you smile.

    I drove H4's with a 2A3 amp and good sub and had no complaints.

    They do look pretty. I’d buy some if they were $10 each. That’s about what they are worth.

     

    There are excellent 6SN7's coming from China. Unless you have heard them your opinion has no merit.

    Hello all - looking for a little help/guidance. Im still relatively new to the 2 channel home audio world and have been trying to do my due diligence over the past year in researching all that I can.  

     

    I currently have a pair of KG3's and a small tube amp (Musical Paradise MP301).  

     

    I seem to be having terrible luck finding a set of any Heresy's, Cornwall's, or La Scala's. Its almost like no one wants to be bothered with basic questions, they play games, or they don't want money in general. I have almost given up for now on speakers and begun looking at amps. Specifically the SS McIntosh MC2100 or 250. The tube stuff is WAY out of my budget. 

     

    I figured, maybe a new amp would make my current speakers a little better. Which is what brought me to the question - what to upgrade first? Should I hold out for the speakers, or take a chance, pick up an amp, and hope for the best with the KG3's for the time being?

     

    Any help you guys can provide is greatly appreciated.

     

     

    You can get a B stock pair of American Walnut Heresy IV's on the auction site from a Klipsch dealer for $2200 shipped, no tax. They will work well with your amp and will be plug and play. They are excellent speakers. I drive mine easily with a 3.5 watt 2A3 amp. My 2 cents.

    Most amplifiers are voltage feedback devices.  Transconductance amplifiers (such as the First Watt F1, F1J, F2, and F2J, etc.) are effectively current feedback devices--like the modified Howland "current pump" circuit (which any amplifier can be turned into using external networks).  There is an interesting book on this subject:

     

    51vzOuc6A1L._SX331_BO1,204,203,200_.jpg

     

    The reason why I mention this is not to disagree, but to point out that acoustic drivers of the types used by Klipsch are all current-driven devices.  The problem, of course, is by using only voltage feedback amplifiers, you also introduce the effects of load back-EMF, which sounds like distortion. I have been exploring the use of these type of amplifiers for driving large compression drivers in order to clean up the output to free it from the effects of back-EMP feedback.  There are downsides to using these type of amplifiers for bass frequencies, but the subjective fidelity gained on HF drivers/horns is documented...by Nelson Pass.

    I want to hear theForte IV. I had III’s but preferred and kept Chorus II before ultimately moving those on also. Maybe the Forte IV will have the best characteristics I preferred from both the Forte III and Chorus II.

    I'm sure they will be better. I went from H3's to H4's and my non-audio GF said 'these sound really good'. The H3's got a phase plug on the tweeter and Tractrix horn on the midrange. I wish I had room for these.

     

    So, go have a listen and leave the credit card at home. 😉🙃😍

    for Heresy's iv, I would strongly recommend an SET amplifier, with few wpc, it will really make them shine.

    I use a Dennis Had SET amp, with 6LS Tungsol's, new production, big tubes, excellent sound. I also use the matching pre amp by Dennis Had.

     I agree. Being new to tubes the OP should look into the Inspire amps. They can use 6V6, 6L6, EL34, 6550, KT88, KT120 and KT150 tubes. The big plus is that the amps are single ended and they only need a pair of power tubes.

    Hi,

    I'm wondering if people have ever had problems with there system being TOO transparent? I’m mainly thinking in terms of   a system revealing less then great engineering or mastering from track to track. Anybody find themselves gravitating to music they know is well recorded rather than music they may like, but can’t stand the bad recording?  High transparency is hearing everything, warts and all.  Has anybody addressed this issue when choosing gear? Example, using a less transparent Dac with a very transparent amp/preamp or vice versa? My question is a little muddled but hopefully you get what I’m bringing up.

    thanks for any perspective on this, Ted

    Hey all - I have a system that I've been using for a lot of years solely for vinyl playback and it's given me a lot of enjoyment.  HH Scott tube amp, K-horns, and nice Technics turntable.  Recently I added a Denon CD player, and was really surprised at how nice it sounded.  I'd like to use a laptop to try to stream Spotify or Tidal... but am completely clueless as to what the optimal set up would be.  Not looking to spend a lot of money, and basically just trying to get something that sounds as good (or better?) than the cds.  Any direction/suggestions would be much appreciated.  Just too much info and not enough time to research this myself.  This community has given me incredible advice in regards to setting up my current system, room treatments, etc... Hoping it can come through again!

     

    Thanks in advance!

    I'm considering upgrading my external phono stage to the iFi Zen Phono stage, which is still budget, but gets pretty good reviews. It comes with a standard ifi power supply, but there is also an optional higher quality iFi power X.

     

    First, the iFi Zen Phono ($149) stage itself: "Unusually, the ZEN Phono has its own high-tech clean power supply. It creates a 1.2MHz power supply (20,000x mains frequency of 60Hz). In this circuit, a 10uF filtering capacitor = 200,000uF at lower, audible frequencies. With serious levels of noise filtration, it performs at the level of well-designed LC filtering circuits as found in classic tube amplifiers. Further, located on its own ‘island’ PCB, it is isolated so there is no noise pollution of the analogue stage." https://ifi-audio.com/products/zen-phono/

     

    Then there is the optional iFi Power X ($99): "The original iFi iPower provides an effective, clean power solution for noise in your system. But why not push your power upgrade to the max with the all-new iFi iPower X? Our new ultra-low noise AC/DC power supply has be optimised to take  advantage of new knowledge, components and tech in the world of super high-frequency power supply design." (https://ifi-audio.com/products/ipowerx/)

     

    I've read some user reviews saying that esp on good recordings, the Power X adds noticibly more 'blackness' when spinning vinyl, but also when using with a DAC. Some say that using this power unit on their router, improves the sound quality of streamed music. This last thing makes me a bit suspicious. Is it perhaps 'placebo' and snake oil?

     

    Being technically challenged, I wonder what you think of this Power X...

     

     

     I used the first version of the iFi power supply with an Arcam rPlay and the SQ was improved. I'd get it and return it if you don't hear a difference.

    It is in both channels. There are 4 power tubes, and 2 driver tubes that all have mates. I can send you a photo of the amp if you want? I have also reached out to the builder to see what they say too.

     

    Have you cleaned the tube pins and the sockets in the amp? Dirty pins or tube sockets may be the problem.

    So, there was a teensy hum when I was using the Schiit sys with the Will Vincent St-70 and was not audible during a song, only in between or when no music was on. but now that hum is WAY louder with the Aretha in all areas. 

     

    The Shiit has no gain, the Aretha does, and the 'noise' is amplified. There is likely a noisy tube in your amp.

    Woot!

     

    Got the new Erhard Aretha Pre......got it hooked up and ready to go.....then lots of noise in the La Scalas.....and what I mean about that is I heard a feedback noise in the speakers when there is no music playing and when there are quiet parts of music....is this to be expected? Or am I doing something incorrectly? 

     

    Here is the chain: laptop, hooked to Music Fidelity V-Dac, hooked to Aretha Pre amp, hooked to Will Vincent ST-70 hooked to the La Scals via 10awg silver coated copper wires bare end.

     

    The build quality of these units are great! Iooks rad too, and when I dont hear the "feedback" sound  it sounds lovely. 

     

    So, again new to tubes and want to know if this is what comes with the territory? 

     

    Thanks! 

     

    I have the same preamp and it's dead quiet on my Heresy 4's with both of my tube amps. There should be no 'feedback noise'. Did this ''noise' just start when you received the Aretha?

    Thank you gentlemen...that gives me the confidence I needed. I recapped the Belle's CO networks with Crites Sonicaps so this leads me to think I can get the Laurels running myself. Is there any reason to think there may be better main caps than what Ron used? If so is it reason enough to do it and will it make a sonic difference? Gonna go find my head lamp cause the variac is out for delivery. Woohoo Thanks again

     

    If you liked the way the Laurels sounded just use the same caps. Replace all of them to avoid future problems.
