Amp vs preamp question
" the choice of preamp will give a profound, perhaps more significant improvement."I agree the impact of pre-amp will be profound.How exactly does one best go about chosing which pre-amp will be best at this point though?

I owned a Hitachi Class G receiver once back in the 70's when I lived in a dorm and wanted high power in a small package. It had some good attributes but for whatever its worth I would say low distortion and holography were not this piece's streng... 
Quad 12L at low volume
I would assume the actives just get the amplification needs of the speaker right by design and would reduce the need to find a separate amp that is optimal otherwise.Not sure how it would change the basic nature of the speak design though as you p...

Sounds like a common theme is low distortion is good for holography and each company/designer has their own ways of dealing with the distortions they care about most. Each approach has up and downsides. Which is best? Who knows and who cares. If y...

Roger_paul,Interesting.Is doppler effect in an amp a different problem than the one solved by application of negative feedback? If so, how much is it different in terms of the effect on the sound?Thanks. 
Amp vs preamp question
Each piece contributes to the sound.The engineering principle of bottle necking comes into play when "tuning" your system. Basically, this means you make sure the part furthest downstream is not "bottle necking" or limiting performance. Once this ... 
Help mismatch maybe?
"Even an A3.2CR which can be had for around $600 used"... or MF A3CR in about the same price range. I bought exactly for a similar bass/loading issue with my larger Ohms and it really nailed it. 
Electrostat - M-L; Quad or Soundlab - reliable
I've read Ohm Walsh speakers referred to as Quads without limits, ie they sound much like Quads with better dynamics and can take whatever power you throw at them and go as loud as you want.I ended up with two pair of Ohms originally coveting the ... 
The Best Amp for the Price of Dirt
I ended up with a Musical Fidelity A3CR when looking for the best for the price of dirt ($600 on ebay) and am still glad I did. 
Quad 12L at low volume
These struck me as OK but not great low volume speakers when I heard them.Triangle Titus 202 can be had used for under $500 and are exceptional, the best small monitors I've heard at low volumes. They can also crank up loud and clear amazingly wel... 
Jeff Rowland 501s burn in ... a strange experience
Sounds like common break in pains. Give it some time to settle in. 
Amp vs preamp question
Matching amp to speakers and speakers to room is most important to get right first. Cost to accomplish this is secondary. Larger rooms will generally cost more to get right.Once you have this planned out, a pre-amp to match can be determined. You ...

Theaudiotweak,I agree with the merits of fessing up to a mistake, but given the apparent severity in this particular case, what other option is there?At least it sounds like it has a chance to work now if adjusted properly. I guess the only way to... 
Reagrding the Ohm Walsh F & A Now Walsh TLS-I, II
Well, I could really use a government bailout, but I guess I will just have to wait in line!Otherwise, I'll be looking forward to an opportunity to hear your creations someday!Enjoyed the website thoroughly!

I don't know for sure whether the H Cat does what it claims or not since I've never heard.But my understanding from their web site is that they sold early models of a device that requires adjustment to work right without any way to perform the nee...
