Kharma CRM 3.2F vs. Avalon Eidolon and Diamond

I haven't followed this thread for a while but if Audiogo2000 is still following it, the front ends I had through my doors for audition were:

Accuphase DP85

Levinson 31.5 and 390S and

Wadia 860

Well this is what makes the world go round. The best tweet I have heard so far would have to be the Raven 2.0.

Although I live in the Netherlands I have no experience with the Kharma but I own Avalon Eidolons for 2.5 years.
The woofer of the Eidolons is very laid back, stiff, somewhat reticent : you need a big amplifier to diminish the reticent/dull character. I have a Spectral 250 power amplifier which is very open, fast but the authority is missing.
I tried a Pass 250.5 briefly and even this small Pass amplifier has more authority at low frequencies.
But the Pass gives a dryer ambiance and is less smooth and is somewhat static. I think that I prefer the Pass for big classical orchestras and the Spectral for vocal and jazz.
I heard that diamonds have the same woofer but with a stronger motor which is 2 dB more efficient. Total efficiency remains the same (87 dB/1 Watt) however.
Furthermore placement is critical: I prefer different distances to the backwall for classical and pop: if the distance is one inch to much the sound becomes too thin (midbas) for classical and if the distance is one inch less I get too much bas with pop music.

I own Eidolon for almost nine years since it was introduced to the market. It is highly sensitive to placement and room accoustic. I remembered, for once, changing my backdrop curtain - a slight more thicker fabric, and the sound got suck up so seriously. It is also that sensitive to placement, even up to a slight move. With proper placement and the best electronics components you can feed, it never sounds thin to me. I have enough bass, deep and extended. The mids and reproduction of human voices are spooky and neither sounded thin to me ( a strong evidence to rebut mediocre mid bass of a ported design). It is so highly sensitive provided if only you hit the right "sweet" spot in term of right combination of components, placement and room accoutic, you would never able to exploit its full potential performance. When it comes to this level of performance, I believe it is more of a personal taste and choice. So, sorry to say that, it is absurb for someone to put so much negative comments to these speakers without hearing one with better setup.

In response to Vincentkkho,

I did hear the Avalon Eidolons once 5 year ago at a dealer and they sounded very dynamic in combination with a Spectral 150S, Spectral DMC 20 and Mark Levinson CD player.
But I heard them at other demonstrations recently and they sounded undynamic to me. The recent demonstrations were set up in a hurry I guess without paying enough attention to placement and room treatment so offcourse you are right about hitting the right sweet spot.
At home my experience is that the more I play the more dynamic they sound. That is why think there is a certain stifness of the woofers. Maybe also the humidity/temperature/electric mains plays a role.
I saw an article on Internet comparing different speakers (horn speakers from Germany), Kharma, the Marten Design, Sound Lab, Avalons Eidolons and Wilson Speakers and they had the same conclusion about the relation between reticense/laid back character of the midbas and amplifier power for the Eidolons. They also said that they expected that the design of Diamond version (and the newer Vision) is an attempt to solve this problem.
Furthermore: If I remember it correctly the test of Martin Collems of HFNRR mentions a certain darkness/dullness.
I have changed one year ago from thick carpetry to parquetry to get a more lively/less dull sound and that helped a lot for the high frequencies but of course did nothing for the midbas.

If you have a Spectral/MIT/Avalons set you will have a nicely balanced combination: the ingredients of the combination are not neutral but the total sum is (dependent on the room and placement of course).
So what is your combination?

I bought the Eidolons because I had electrostacic loudspeakers for about 20 years and I wanted 3-D electrostatic sound without the huge dimensions and necessity to use class A OTLs (I had 200 Watt Fourier Pantherres OTLS) to power them.
But nothing is perfect in this life and the Eidolons certainly are not. Eg with the change from Martin Logans Monolith-3 to the Eidolons the quality of the bas (eg piano) improved a lot but the enjoyment of listening to Baroque music decreased somewhat. Electrostatic speakers with tube amplifiers are per definitions optimal for Baroque.
