Hi to you all.

I am brand new to this forum and would like to thank the community in advance for all the great information I have already found here.

 

I'm turning to you because I'm pretty disappointed with my local hifi-specialists. It seems that no one really knows how to approach the Fortes. 

 

I am looking for a suitable solution for my stereo setup. I currently have a Denon AV amp (6500) with enough power that I use for home cinema. I have a 9.1 T+A HighEnd Speaker environment set up which is great for cinema. The FL and FR are my Klipsch Forte 4. 

 

Since a few month I use 95% of my audio-time with the Fortes for music only. All kinds of sources but i have not connected my MM yet. The readon is part of this inquiry.

 

And surprise surprise;  I can't get the  quality and depth out of the highly digitized Denon that I'd like to give the Fortes to sound as they should.  Stereo sounds flat, cramped, at the limit, the highs struggle and the basses drive in the minimum. Mids are ok. 

 

I had already connected and tested various integrated amps and power amps to my preout and tested them, and the result was what I had hoped for. But I have not found the perfect match.  

 

Now the question is, if you could give me a recommendation from your side? I'm wavering between a power amp and an integrated amp with tone control and, if possible, a bypass for the tone control. Tone control therefore, because I want to re-define the linear sound of the Denon myself. Bypass/Tone Off because I would like to integrate the Speakers into my 9.1 setup, obviously. 

 

Of course, this is not possible with the PowerAmp. Of course there is also the question of Tube, Class A, Class AB etc. But there I am rather stress-free. As long as my Fortes are served well. But dize matters to me. I would like an amplifier in the standard hi-fi size, not a Mini or Compact sized device. I have a nice and ventilated cabinet.

 

My budget is somewhere around 2500 USD / 3000€. But currently i am running circles. Integrated amp vs. power amp ? And if Power Amp, which one and if Integrated which design (Hybrid?) Or even a Vintage Device such as the Pioneer SA 9500ii ? Nice device but my local hifi-geek does not recommend it for my purpose (!?). He recomments the Cambridge 851W which is a 350WpC Power Amp. Foes this make sense? Not to me (yet). 

 

Long story short,I am grateful for any advise to make my decision easier and help me out of this forest. 

 

Btw; listened to T+A Class A which was good but unfortunately not perfect from a connectivity poit of view (no main In). Parasound Hint 6, Magnat MA 900, Vincent 237 Hybrid might be something? But the differences in performance and features are so enormous that I am confused. Only Parasound provides Tone Control and even SubOut. But I can't test it over here. 

 

Any hints, ideas, suggestions? 

 

Thanks

I am using the Parasound Hint integrated with my Heresy IVs and have been very happy.  This Class A/B amp sounds amazing.  It has a good quality MM/MC pre-amp.  Admittedly, I am using it in a 2.1 setup, not as part of a home theater; but as you have seen it has the bypass for that purpose.  Several online sites, music direct for example, have return policies so that you could audition it in your room.   Good luck.

For my Forte 1's, I combined a tube amp (Dynaco ST70) for the mids and highs and a vintage Pioneer (SX-1980) for the woofers.  Great combination for me.

 

You didn't state what type of music you listen to.  I listen to heavy metal, so the chest thumping bass is a requirement which the Pioneer can deliver.

Thank you claytonpd. This is exactly what I thought and I really like the Parasound sound. Unfortunately I can not test it here but I keep the Hint6 times on the shortlist. I have heard so far only good.

Vintage Pioneer is always a great match with our speaker brand

I am also convinced of this. Just strange that a dealer offered me a Class D with 2*350 wpc as an alternative to the Pioneer. He said I needed a very powerful SS for the Klipsch. Which is total nonsense at 99db. Thanks for the confirmation.

There's nothing wrong with your amp, IMHO, it's as capable of producing a well focused stereo image as any other modern-day amp..  

 

I suggest repositioning the speakers and perhaps your listening chair/ sofa. ..And give thought to room treatments to manage reflections.

 

Imaging has a lot more to do with room setup than it does amplifier choice.  ..Now if you're just looking to change out your amp b/c you want something different to look at, play with, etc..  ..There's nothing wrong with that at all.  But don't expect that alone will improve sound.

 

If you do decide to change amps, I strongly recommend an integrated.  These days, there's absolutely no reason to divide b/w two components that which can be combined into one.  Today, integrated amps have S/N ratios, channel separations, and THD specs that are well below our hearing threshold.  ..If you like the look of two components and you don't mind the jumble of additional cables, then fine.  ..But it would be a mistake to think separates will sound better just because they are...  well.... separates.  

 

Something people don't often consider with separates is that by having separate grounding points for both pre and power amp, and by introducing a pair  of interconnects you potentiate  hum/hiss issues that might not be there with an integrated.  This was true for me!  Both my Bryston (BP25 pre/ 3bsst amp) and my B&K (can't recall models) pre/power amp combos were plagued by hum issues that could only be dealt with by fiddling with position of the the interconnects.  My three integrateds were much quieter w/ less fuss.

Analog Tech Plateaued in the 1970s or early 80s

There are lots of great choices from this era

when Stereo was king, and

manufacturers had the best engineers money could buy

Even today, every Engineer would jump at designing audio electronics.

 

I would look around for a mid power 40-75 Watt integrated from this era

there are so many of them

one that has already been rebuilt

or a mint unit that goes in for a recap and rebuild the day you buy it

These units are proven and well known and low tech

Metal cases, transformer and displays don't age under normal circumstance

Get one with tape in, tape out and you can use an equalizer or other high performance processor

$300 used in good working condition

 

Mandatory

Tape port-s

1 tuner port

1 or 2 Aux ports for DAC

1 or 2 Phono Ports MM or MM& MC

 

Dual monoblocks , 50W are a niche with a cult following

Kenwood, phillips and others

these sell very fast

 

So many choices

Yamaha, Pioneer, McIntosh, Kenwood, Harmon, Marantz and so many others

Most, all, have MM ports or you can go outboard for $150

 

If it cost $350 in 1970s = 10 OZ of gold

2022 10 OZ gold = $1,800 x 10 = $18,000 amp

I have a bunch of older surround aps

basically stereos with surrounded grafted on to them

some were $4000 new and sell for $50-100 now

Turn off all of the surround and processing

what is left is a really good stereo.

 

Modern surrounds in direct mode can sound great

some Yamaha's have stellar specs in direct mode

and the DAC is built in

The Forte's love tubes. Try it. You'll like it. Look up the Willsenton R8 reviews on Youtube. 

Thank you! Willsenton sounds like an option, indeed.  I have not been in tubes yet, but I am actially leaning towards it.Whereas I almost like the Willsenton r800i even better. That one comes in 2 versions; B300 845 and 805. I understood that, the 845 tube would be better than 805 for high sensitive speakers like ours. I'm still too little into it for a rolling, but i'm getting there.

i would just make sure that the lower powered/SET tube amps can handle the impedance swings -- the forte iii went below 4 ohms as shown below from stereophile.  i couldn't find any published measurement for the forte iv . . .  these impedance drops (with high phase angles) can be hard on tube amps.  i experienced this trying to use a jadis orchestra black with cornwall ivs -- mids were gorgeous but no bass.

You are absolutely right. Thanks for the heads-up. A similar effect applies for the Forte IV. A little more linear than the III but still.  The measurement of the IV shows a rather wavy impedance curve, which then increasingly rises in the horns' area of responsibility. In order for this not to be reflected in increasing levels, the (tube) amp must already exert a certain control, which some  small output transformers simply do not have. The impedance drops to 3 ohms at 300 hertz.  At 100 Hertz, the amplifier power supply is loaded with an EPDR value of not even 1 Ohm. Only a few amps can cope with this. 210708-ipro-klipsch-forte-4.thumb.png.de230810ebf4573b39726b2daec9c9d5.png

 

This said, one should pay attention to a lightning-fast pulse processing. Perhaps this is the reason why certain dealers have recommended powerful amplifiers such as Cambridge Audio 851W. strong output power can increase much also the impedance processing. Or in Tubes this would speak for something like the 805A triode.But I now actually see a certain risk in the area of tubes as well.

If you go retro

when you recap, be sure to increase the capacitance of the power supply filter caps

I increased one of my Yamahas 30% staying in the same footprint.

The rest of the electrolytics, one over on the voltage rating is a good idea

A lot of people are reluctant to increase capacitance other than the main filters

 

Most are capacitor coupled other than McIntosh with massive output transformers

I have forte 4’s.    I have tried these speakers in my house with both the moon Ace and a audiolab A6000 play that I’m demoing.   I considered a schitt stack but the idea of 5 boxes (streamer and phono) seems too difficult and cluttered.  I have a Laxman tube amp on order but it’s like a four month wait.  All in all  The Ace is a great solution……powerful,  no hassle use and softens up the fortes highs.   Unfortunately I borrowed the ace from my primary system,   So I’m still shopping for the fortes.
If the audiolab was given to me I would take it,  but I definitely wouldn’t buy it. I would rather spend a little bit more money and get something that I would be happy with.
