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.

Audioconnection, there is approximately three and 1/2 feet between the sides of the entertainment center and the side walls with the speakers approx 1 foot away from the sides of the entertainment center. They are forward of it by 1/2 foot with the transducers about 4 feet from the back wall. Also I actually found that toeing the speakers in more than the ML inside 1/3 rule works better for me. As soon as I have one of my grandsons available to help remove the heavy bridge between the towers on the entertainment center I will reinstall a tube DAC and not do anything else until I see how that works out.
I would look into Atmospheres amplifiers for Electrostats , over the years I have listened to a few systems using Atmophere amplifiers and preamps that I thought were very good match with eletrostats , this pass holiday season a real surprise was Atmosphere M1 preamp and 60 watt monos driving Reference 3a Veena B and source The Beat turntable , very impressive indeed .
Broadstone,
I only saw Atmaphere's post now and I cannot emphasize enough to read his post carefully and to follow his advice. He is an expert and he knwows what he is talking about.
Here you have knowledge and experience versus just opinions and predelictions.
@Atmosphere, I have been mulling over the 'Zero's' as one possible solution to an impedance preference for an 16 Ohms output, which is unfortunately, a winding not available to me from a potential replacement amplifier that I am currently demo-ing.

Amongst the many plaudits for the Zero's, I have however noted one or two comments that make mention to a perception of a *very* slight degree of smearing to the presentation

I would be most interested in any considerations or experience that you may have on this matter.
