Musical full-range in the $3-4K range used?
Duke sold a set of speakers to one of my friends here in town, so I got to hear them in my system before delivering them. I really was not prepared for how good the speaker was! Very well integrated, good bass extension (into the upper 20s to my e... 
The best phono stage out there?
Jcarr , we certainly agree about that! There are so many things that have to be taken into account that any designer that focuses too closely on any one aspect may well be doing so at his/her own peril. I think, like you (I imagine), that while it... 
Al Stiefel of RMAF Has Passed Away
Al and Marjorie have always been special to me. I've always been grateful for their work on RMAF. I was really shocked and saddened when I saw the announcement this afternoon. All the Best to you, Al! 
The best phono stage out there?
Jcarr, while I agree with most of what you have said, and I also feel that its a bad idea to make generalizations, especially in **this** sport, I can safely say that I have yet to see a decent circuit where feedback was also a good idea. Certainl... 
Tube amp recommendation
Hi Jax2, my point has to do with equipment matching. An SET driving a 92 db speaker is going to get clipped a lot if you listen to demanding musical passages. On a speaker like that, you would need a lot more power- 60 to 100 watts, in order to ge... 
Tube amp recommendation
FWIW if the amp is good, its good with rock, hip hop, electronic, classical- whatever.Contrary to opinion above, the size of the woofer and the ability for the amp to control it really is a red herring. A small amp controls a big woofer just fine.... 
The best phono stage out there?
Hi Ecka, active phono EQ works inside a feedback network in the phono stage (the feedback takes a bit of the output signal and feeds it back to the input). Because the signal propagates through the phono section at a very finite speed, the feedbac... 
Coincident Victory or Eminent Tech LFT8
Coincident got a rough ride from Stereophile years ago if memory serves. Like happened with a number of other companies during that era, the Stereophile comments were undeserved. On account of that, Stereophile developed a reputation in the indust... 
Help me get the most out of my Merlin TSM MX
Hi Bobby, I think you have been using OTLs longer than that- it was at least 10 years ago that we first showed with you (in that time, FWIW, we've made a lot of progress- the newer amps have a lot more authority and are smoother with more detail..... 
Help me get the most out of my Merlin TSM MX
Another way to make sure you are getting the most out of the speaker is to use an OTL. Either the Merlins were designed on OTLs or else the speaker was designed to be very tube friendly. I would not mind finding out how Bobby has used OTLs with th... 
Solid State Amps for Quad ESL 57?
Mrtennis, the only way I've seen proper bass out of Quads with transistors was when the panel was too close to the rear wall. At the same time the highs were dreadful- harsh and lacking real speed. I have trouble believing something like that coul... 
The best phono stage out there?
Noise floor is not the final word in phono stages by any means. Some phono stages are quiet, until you put on a record and realize that there are an awful lot of ticks and pops. Other phono stages (usually ones with passive EQ) may have a slightly... 
Help gaining knowledge on SET
FWIW unless you really listen near-field, not many SETs are going to work with a speaker that is only 91 or 92 db. SETs in general don't make a lot of power- 22 watts is a big one, and 22 watts will not do the job on a speaker with efficiency that... 
Solid State Amps for Quad ESL 57?
Hi Sarcher30, in the case of transistor amps, the ideal is to be able to deliver the same output voltage regardless of the load impedance. That being the case, then a 100 watt amplifier driving 8 ohms will make 200 watts into 4 ohms and 400 watts ... 
Solid State Amps for Quad ESL 57?
Hi Sean, Whatever that was that you read is misleading- it violates Kirchoff's Law, the law of electrical energy conservation. IOW if you put 100 watts into 4 ohms or 100 watts into 8, the output will be the same if the speaker efficiency is the s...
