The signal tubes for the RM-200 need to be very carefully matched and balanced for the circuit. Roger is the only one who can get it perfect so you should consider RAM tubes as your source.I work with Roger and am currently using his personal RM-2... 
Lightspeed Attenuator - Best Preamp Ever?
Well I see no reason why either of those sources would pose a problem for the Lightspeed. Glad to see the JLTi is still around as well. Listened to one a while back and enjoyed it quite a bit. Great bang for the buck. 
Lightspeed Attenuator - Best Preamp Ever?
@chakster, what phono sources would you be using? I think this will have some bearing on the result. I have heard the B1 but have not been able to compare it to my Lightspeed. I have compared my Horn Shoppe Truth buffered preamp to the Lightspeed ... 
6 ohm speakers with 4/8 ohm amplifier
It's about damping factor. The 4 ohm tap will increase the damping factor, most speakers are designed for this, better control over the woofer. However, you may not like it so as suggested try them both and see what you prefer. 
Speakers least affected by room acoustics
@recordchanger2018, I got off the acoustic treatment train a while back. It started when I bought my Quad ESL 57 panels. The previous owner used them in his design winning home that was featured in an architectural magazine, the name of which esca... 
Small room electrostat/ planar speaker?
@ralphAppreciate the advice and spoke to Bruce but he is no longer selling panels separately. Too bad, that would have been ideal for my project. 
Small room electrostat/ planar speaker?
@ralphThanks I was wondering if I could just get the panels. I think single panels would be fine given I have Zeros. 
Small room electrostat/ planar speaker?
I believe the Russian 6550s were the original Svetlana brand that went out of production when the factory was destroyed. The RAM 6550s are Chinese. If they don't have them have Sheila call me and we'll get some to her. We have RAM, Svetlana and GE... 
Small room electrostat/ planar speaker?
If you haven't already tried them use 6550s in the 200. It was Brooks Berdan's favorite tube in both the RM-9 and RM-200. Roger kept a special stock of 6550s for Brooks, old Russian ones that if I recall did not have a getter. Alas, no more, but I... 
Small room electrostat/ planar speaker?
Well it is tempting but I do need a 100 Hz crossover point. The AirSpring woofer system I use was designed by Roger Modjeski and the crossover is the Beveridge RM-3 (also designed by Roger) with 100 Hz 4th order Link-Witz Reilly low pass filter (3... 
Small room electrostat/ planar speaker?
I'd be much more interested in these speakers if I could use my active crossover with 100 Hz high pass and low pass boards with them. I would send the high pass signal through my tube amp to the panel of the LFT-8b, then the low pass through my so... 
Oomph or pressure?
The complaints often leveled against “passives” relate to problems with dynamics and drive, as others have mentioned, but those complaints pertain to resistor-based passives, not magnetics. I have resistive, opto-coupler, photo cell, transformer... 
Preamp to Headphone transformers?
I actually use a Stax SRD-7 that connects to the speaker binding posts of my amp. The SRD-7 allows me to switch between speakers and headphones. I have another device that allows me to do the same with dynamic headphones, but no switch so I have t...

Looking for vintage Quad ESL's - or my wife thinks a "shrink" becase she says I'm crazy!
You can buy all the parts necessary for your Quad 57s on eBay or directly from Kent at ESL. You would need the protection circuit board and while you are in there might as well install an upgraded power supply board. The parts are reasonably price...
