Best tube amp for electrostatic speakers

For over 35 years I've almost exclusively used either ribbons or electrostats with solid state amplification and have been generally happy with the sound. Over the last several years, though, my hearing has become somewhat degraded and more sensitive to certain frequencies. The frequencies which seem to cause the most discomfort occur in the 1400 to 1900Hz range and come across as "bright" to my hearing. After researching this matter and having been given some expert advice, I've decided to pursue the idea of replacing my present amplification equipment with tube based gear.

The purpose of this post, then, is to solicit advice regarding the best approach to making this decision based on the following information: the current basic equipment is Shanling Solid state CD player, Peachtree Audio Nova used as preamp, two DBX 1531 EQ's to help compensate for age related hearing loss, Peachtree 220 amp, Silversonic T114 cable and Martin Logan Ethos speakers.

The listening area is our living room measuring 15 by 22 feet with my listening position 16 feet from the plane of the 2 speakers which are positioned 11 feet apart measured center to center. Located between the 2 speakers is an entertainment center which is about 9 feet wide. My listening interests are varied from solo guitar and light jazz to occasional orchestral music. I don't generally listen at high volumes and am not particularly interested in strong bass except for the rare action movie background.

Unless not advisable for some reason, I would like to keep the Peachtree Nova as a preamp because of the significant latitude for source connection and what seems to have a decent internal DAC. If this option would substantially defeat the purpose of the intended modification I would work around it. I can no longer deal with sounds that are "bright" which I now find uncomfortable but detailed sound is very important.

So, the questions are: is the move to tubes the best option and, if so, what might be some reasonably priced amps that could accomplish the goal. This, of course, would take into consideration room size, etc. for determining power requirements. If there are other more practical and less expensive options to consider, I would appreciate that advice as well.

Broadstone,

"To answer one question regarding the comparison of live versus recorded music, especially using the piano for reference, we have a piano and, yes, the same notes either recorded or live create the same discomfort. This fact, of course leads me to the conclusion that it is not a component of my system that is the culprit for at least this issue."

Looking at the above quote, the one thing that stands out is the fact that you have the same problem when you hear real instruments live. I think there's a very good chance that you will not fix this problem with equipment. Think of the live piano as the best or perfect stereo system there is. There's no where else to go. If you want to continue to listen to music, you may have to go in a non audiophile direction. Maybe just something for low volume background listening, or something similar. I wish that I was able to suggest some better options for you, but I can't. Hopefully, someone else will come up with something.

I think Clio09 came up with the answer if the OP really wants a tube amp, the Music Reference RM-200.
In that it has 1ohm or 2ohm speaker taps, there is a proviso though, will it still have the watts to get to a reasonable level when driven off these taps, the wattage goes down the lower the impedance tap is used.

Cheers George

I may have started this thread under the false pretext that I have a strong desire to switch from solid state when what I really needed was help with certain specific issues thinking that tubes may be an appropriate path toward that goal. What I'm learning from the resulting discussions, especially in consideration of the range of opinions from experts regarding how best to use tube amplication with ESL's, is that my most practical choice is to stay with solid state.

Although my system may not be "state of the art" as was pointed out early on this thread, it is one of the best sounding setups I've had in my home for over 50 years so I'm generally pretty happy. For these other concerns I'm going to reinstall DAC's at my two primary sources, play around some more with the equalizers and worry about upgrading amplification later.

Zd,

Well, there you go then. I don't doubt it can be done with the right amp and sound very good. I'll keep my eyes open for a chance to hear ML and tube amps myself.

Hello Broadstone
I own NAT SE2SE 211 tube amps and personally these have been an incredible match for my Soundlabs. I feel like screaming from my rooftop how lucky I feel to have FINALLY found the amp that for me makes my babies sing. Now this did not happen overnight. I have owned my Soundlabs since 1999 with no modifications,no new panels and no updated backplate and I can tell you if you get the"right" amp,power cords,interconnects or whatever to make electrostatic speakers sing you won't listen critically anymore. It takes time and it make not happen very soon but don't give up. I really don't think many who own electrostatic speakers have really heard what they can do if "everything" is right. In other words, they just "settle" for the so-called best big name instead of trying to get them to sing correctly. I passionate about my babies because I am transported to another realm. I am not here often because I am "listening" no need to buy anything else or debate.
