Used Atma-Sphere M60-MK111 Tube Amplifiers
Contact Ralph Karsten at Atma-Sphere. He can tell you exactly what you need to know. 
good hifi store in Bay Area
Tone of Music is my favorite but doesn't carry B&W. However, the Devore's sounded very nice when I was last in the shop dropping off some tubes for Tim.

can you find the thread. I had no luck. Here you go:https://forum.audiogon.com/discussions/st-70-best-sounding-version/post?highlight=dynaco%2Bst70&...Someone asked about the differences between an RM-10 MkI and MkII so perhaps you can educate...

I can say from Roger's perspective that while he listens to digital sources, I am not sure he would comment on their circuit designs given his lack of interest in manufacturing such a unit. Roger is all about research first and foremost, as a grea... 
How to record from lps to tapes
Have you tried going from the Allnic output direct to the input of the Otari and then the Otari output to see if the volume level is different? This is how I have done recordings using my digital source to tape, even though my preamps have tape lo...

@ieales - Thanks for digging that up. From what I read in the link if the B4 kits were to be available in March or so, then they are either quite delayed or perhaps they were made available and sold out. I have the SL kit on a fully populated boar...

@ks2 - When Roger refurbishes an RM-5 the preamp gets computer tested pre-end of Soviet era SLN 6922 tubes. That is the preferred tube and the lowest noise 6922/6DJ8 tube he has tested.FWIW - I have used them in my RM-5 Mk IV, RM-1 (12 tubes total...

I hope that Roger will step in at some point and address some more questions but currently there are a couple projects occupying a lot of his time. So he’s had to take a little break from here.@4krow - Roger has often talked to me about the diffic...

Yes was aware it was a First Watt product just never saw it advertised as a kit. Nelson does have a crossover kit on the DIY Audio store but it's an analog version of the digital crossover used by Ziegfried Linkwitz, who asked Nelson to design it....

@bdp24 - where can I find that B4 crossover kit you referenced. Haven’t been able to locate it on the Internet.

@bdp24 - especially on this day, but my thoughts exactly.

@fleschler - sounds like you are trying to pick a fight with Roger, or perhaps bait him. Seriously, you should re-examine this tactic. 
Monostrapped Atma-sphere M-60
Based on the video I don't think the M-60s are set up for such operation unless they are modified and only Ralph will be able to say if that is possible. Why not get 4 x M-60 and biamp instead (although it could be helpful to get a pair of Speltz ...

@atmasphere - I can't seem to find the reference you referred to on page 12. What I did find was this which Roger wrote:I would have had the electrician put in several duplex outlets so no power strip is needed. Power strips vary in cost and qual...

ramtubes - So, you don’t believe power cables make a difference other than connectors and isolation transformers are worthless? Is that correct?I don’t think he is saying connectors make a difference sound wise as some people might lead you to bel...
