    Curious to know how a class D amp can sound, I did some research and inquiries and the Tpa3255 board seemed like the best choice. I found a very affordable one on Amazon.

     

    Fosi Audio TB10D 600Watt TPA3255 Mini Amplifier HiFi Stereo Class D Amplifier Integrated 2 Channel Digital Audio Receiver for Passive Home Speakers with Treble and Bass Control https://amzn.eu/d/0DF2Cst

     

    I received it yesterday and tested it on the Lascala with my brother. We had been listening to a SET 300B for a while before trying this D class amp. It doesn't sound bad, especially considering its price and size, let me be clear about that!

    But... If we judge the amplifier with an audiophile's perspective, it falls a bit short. The sound lacks body, has a slightly harsh tone, and isn't very musical.

    I find it hard to believe that this would sound as good as a decent SS amp (I have no experience with SS amps).

     

    Now, I'm not entirely sure if my initial impression of a D amp is accurate. Could it be that I bought a too inexpensive amplifier and the PA5 will sound better? Given the price difference, one might think so. However, on the other hand, there's nothing particularly exceptional in such an amplifier that could make a significant difference, in my opinion. It consists of a power supply and a board.

     

    Does anyone have thoughts on this?

    I'll give you my thoughts, since you asked. The TI 3255 Chip is an amazing device. Just how well it's implemented in lower wattage than the "max" rating makes the difference. Everyone is barking up the wrong tree about this. 

     

    You "ahem" review reminds me of the You Tube video from a fauxtographer and his cute wife testing out all the 85mm lenses on the market, photographing a mannequin head. They then declared a Nikon 105 MM to be the winner. What an insult and a waste of time.

     

    If you are all about all horns and big horns, like I am, you already know that big watts don't mean a thing to a Klipsch guy or gal.

     

    Also, this is an old PA-5 thread, so why are you judging negatively an amp that your go "cheap" and not a PA-5?

     

    Emotional testing without data, is just another opinion, especially with all the flowery word BS that comes from StereoPhool and Absulutely Soundless magazines whose reviewers listen to good MUSIC in crappy room.

     

    Waste of time.

    she's so fine..no tellin' where the money went

    Ah yes, Kelly Harmon, daughter of football star, Tom Harmon, sister of Mark Harmon on CSI,  married John Z. DeLorean which made the other GM wives jealous. Gorgeous woman. All the siblings were movie star gorgeous kids.

     

    Anyhow, I photographed JJ without the morning crew and all the WRIF, WMGC, and WCSX Jocks, including Arthur Penhallow, right before he quit the RIFF, because they didn't want to pay him what he asked. But that's another story.

     

    I guaranty you that none of those 3 stations ever played even ONE Tony Bennett song!

    CKLW I remember it well!!! Walking home from school with my AM radio.

    I had a Detroit News paper route in 1968. Like any 13 year old, I loved music and listened to CKLW in Jr. High, which was a 1.5 mile walk each day. I saved money and bought a Zenith portable AM radio and a pair of Koss Brown headphose (they probably had 3" speakers in them). The radio came with a mono ear bud on a wire, so I cut the ear plug end off and wired the 1/8" mono plug to a 1/4" female adapter for the 1/4" headphone plug (wired in Mono, using the bought all this at Lafayette Electronics. Cassettes were just coming along then as a music medium. My dad told me I looked ridiculous with those things on my ears, but they kept them warm in the winter too. I may have invented the first walkman, and my friends think Sony stole my idea. LOL.

    Even on the Duos they produce no audible background noise. 

     

    One other caveat. If you leave these amps on in perpetuity, like for months, one channel starts making quiet “burps”.  Power cycling the amp takes care of that.  Maybe that’s fixed in the redesign. They might be over-crowding the components. I would like to have this amp in a bigger case with the circuitry more spaces out. 

    By comparison, I have used PP (old Scott) and SET (2a3, 45, and more) amps. My favorite were point-to-point wired 45 SET monoblocks, but these PA5 amps hold their own against any of them. They also run more quietly and on a lot less energy. But no, not quite as amazing as a good pair of 45 SET monoblocks - they don’t quite transmit THAT level of detail, but for that you’ll pay 10x more. 

     

    Sorry to jump back in with a bandwagon-like fanboy post, but I figure the experience of using these with the ultra efficient Duos could be useful.

    I bought 3 of them. One spare and the other two in full time use on Edgarhorn Titan II's and in my full Atmos HT/2.2 stereo (at the couch of a button) upstairs with the Danley SH-50's. Yamaha YPAO room EQ on both. Best bang for buck amp EVER.

    The guys that had trouble with them use too much power on INEFFICIENT, non-Klipsch speaker. But we know better!

    Sorry, but I don't quite understand what you're trying to say. Could you please explain it a bit more clearly for me? I'm really curious about your explanation.

    The effective mouth size of a Klipsch Bass Horn is the walls of a room corner, which is 4x4 feet. Since the Undergroound Jublilee and the Klipchorn bass horns were designed for a corner, they become 8 foot long horns. The mouth of a LaScala is too far from the walls to be as effective as the Khorn or the Jubilee in BASS EXtension department. All speakers have Cabin Gain in small rooms (those in most homes) and this is why Klipsch can make shorter horns that take advantage of this.

    He also believes that this setup is perfectly fine and that the difference between placing them in corners or not was hardly audible (they tested this at the store). 
    I take him seriously too, as he has been involved with audio his whole life, and from what I know, he doesn't settle for compromises. 

    Simple answer, really. Having designed bass horns for about 10 years, the Khorn against the wall is only good for 60 hz. or so, which is fine for most music. You can add EQ or a subwoofer below that. It's a 4 ft horn without corners, as is the Underground Jube. The rest is opinion without curves, of which I have several hundred accumulated.

    While ranking the top Heritage speakers, maybe it should be pointed out that Jubilees, the older models in particular, have sometimes been described as "Super-Scalas", having a sound more like a very improved La Scala than an upgraded Klipschorn.

    He shouldn't be. The LaScala is a 2.7 foot horn that cuts off at 104 Hz. then relies on the sealed dog house for bass below cutoff when placed in effectively one "corner" the cabinet, in to another corner or wall, having a "free lunch" from cabin gain. The Underground Jubilee is a 4 ft horn that cuts off at 60-70 Hz NOT in a corner (etter than a LaScala) and behaves better than a Khorn when in a corner.

     

    Even PWK felt the Jube was a step up from the Khorn. Now that Roy has done a "greatest hits" version of it, the "75" with Active Network and better drivers it's the top of the pile. The LS plus twin horn subs is the best bang for buck, but it's a 4-way while the Khorn is a 3-way. Salt to taste either way, it's YOUR taste buds and Wallet.

    Two subs give the advantage of more power, of course, but more than that, they produce a more even soundfield, with much more even bass response throughout the room.  I haven't heard a properly-setup Khorn arrangement, so I can't give a precise comparison, but other members have heard both arrangements, and the Scala + Sub combo is said to give away nothing to a pair of Khorns in ideal corners.  Hopefully, members who have heard both arrangements will check in with their impressions, which can give you more detail.

    I had two pairs of Khorns (Raw Birch and Lacquered Walnut). Also several pairs of LaScalas, with and without Horn Subs (THTLP's by Bill Fitzmaurice). By far, the LaScalas with Subs are better than Khorns without. Islander is right.

    I started with the Heresy 2, and step by step, I'm climbing up the Heritage ladder.
    Jubilee is excluded, but the Khorn seemed like a great end goal to me.
    However, I don't have any corners where these speakers can be placed. So maybe the La Scala was what I had in mind as the end goal.
    Until I spoke to someone who owns the Khorn AK6 and claims that this generation of speakers can be placed fine against a long wall, corners are not needed. 

     

    Now I'm wondering, in my situation where I only have one long wall for the speakers,
    La Scalas (with a possible subwoofer), or the Khorn AK6 (false walls are not an option), where only one side can be placed against the wall.

    Which one is the best option? 

    Just do what Paul Klipsch did (I did too). Build false corners out of drywall and 2x4's. Easy and cheap. It's in the Dope From Hope.

  12. Read and watch the video. I met Dr. Waldrep and bought some of his recordings. Very good work. Even he changed his mind about hirez being better. It's the Recording Engineer and Mastering, so I agree with Artto on this.

     

    ALL HiFi is an ILLUSION, since you can't replicate the sound of any acoustic instrument with varying fundamentals and harmonics with varying 3D dispersions in different recording spaces with only 1 or 2 microphones! It's all an Illusion, so pick your favorite ones!

    If you don't like something you're hearing, on your system (which includes the room) - it's your system. Not the recording, not the format, not whether it's MQA or not, or something else.

     

    Headphone listeners would disagree about the room. MQA is a distorted format, but nothing is ever PURE, as you have so well stated. Dr. AIX pretty much settled (even to himself) with 500 participants that there is Zero advantage to using HI REZ formats because no one could tell the difference between any of them beyond good old Redbook CD. It's the MASTERING!

    Congrats that setup looks awesome. I bet that system sounds fantastic.

    I had a C26 when I was 19. If I'm considered old by now, that pre amp is older, and still works, I presume. But what about the Capacitors? Maybe don't wear like in speakers, but the question remains if it is to full spec?

    That is what I would build if I could afford the drivers.

    I created a flat pack of a modeled "slim" version of the refolded Gjallarhorn. I bought the drivers at a close out sale at PE. The will be done and measured this year. Sims tell me they will go down to 13 Hz. in my room.

    I won't be buying a new C8 anytime in the near future because on Friday I received my Pink Slip for my 2017 C7 Grandsport. Really nice not having that car payment anymore and I just recently hit 20,000 miles onmy C7. Id love to have a new C8 Zray but only if it was free. Im too old and retired to get into major car debt.

     

    I did a story in Rangefinder (they got the cover too) on GM photo department about 20 years ago. I got to see all kinds of cool things not open to the general public. The Photo Dept. Manager is now President of the Corvette Museum where they do a "Museum Delivery" for C8 buyers. At some point and will drive to Kentucky and visit with my camera.

     

    To your point, I don't believe in owning expensive sports cars like Lamborghini, Ferrari, Porshe. Yachts, and Swimming Pools included. I want friends that own those things. I just want to own the set of keys to all those toys. LOL. This includes expensive TUBE amplifiers, too. Been there, done that in my 20's and 30's. Owned them all McIntosh, Marantz, Scott, Dynaco, etc. The "space heater to good sound" ratio lost it's luster for me. I like tube amps that are owned by others for similar reasons as the sports cars, etc.

     

    Back to the OP, having integrity or lack thereof, for sales on a public forum is not excusable.

    @claudeJi - I'd like to see you in a new C8 hybrid - withe the normal 500 HP gas powered in the back with the 160 hp motor in the front - zero to 60 in under 2.5 seconds! All wrapped in a C8 Z06 body - imagine all the chicks you could  pick up in the Motor City!!!! Go get em stud! and $5,000 would be a great deal for that ride.

    You are too funny, man. One of my BFFL's (45 years and couting) has his original 1967 Vette he bought after he got our of Military Service. He sold his lakefront property and bought a C8 cash with 45 Grand leftover. Even with the regular 500 Horse mid engine, this this is a cross between a go-cart and a spaceship. It's just glued to the road like no other. 

     

    So yeah, I think the carbon mirrors package cost $5 grand on that thing, so the rest of the car would be free. LOL.
