Just purchased a pair of Atma Sphere M-60 Mk 3's upgraded to 3.3's
kjack48230,  While you are waiting, I thought I'd offer a few additional comments since they may be relevant to layout of your listening room when you have the M-60's.  If you have talked to Ralph, you probably already know most of this. First of ... 
Where are Conicident Speaker Technology electronics made ?
bigkidz, Excellent question.  My comment related only to the quality of workmanship, since that is the heart of the question with respect to Chinese assembly.   My comment is not a commentary on the design or parts selection.   Point to point wiri...

I think we are wandering a bit, but I think the comments from Charles and Mikirob warrant a response.  I have also become an infrequent contributor, but for the most part, that is not due to an increase in negativity on the boards.  Some of that s... 
Where are Conicident Speaker Technology electronics made ?
I own the Frankenstein 300Bs, the CSL pre-amp, and the little Dynamo EL34 tube amp.  The workmanship inside all three pieces is superb.  I don't know and don't really care where they were assembled as long as the workmanship is there.  On the othe...

Congratulations.  My advice is to proceed slowly in making system changes.  The M60s 3.3s are very revealing.  They are not forgiving of sub par source material, especially bad digital.  Put your new amps in and live with them for 2or 3 weeks then...

@jtcf  Thanks.  I've been through the drill before with the M-60s, and yes, it takes a bit of time, but I have a pretty good feel for what the amps like in terms of 6SN7 attributes at each of the 4 positions, so its not quite as bad as trying to w...

@jtcf, I may well find the same thing when I pick up another pair.  It takes some patience in finding an optimal mixture of 6SN7s in my M-60s.  I'm going to leave everything as is for a couple of weeks to permit burn in before I make a final decis... 
Sofia Electric Blue 6SN7
I received a pair of the Sophia blue 6sn7s yesterday.   Bottom line is they beat out a pair of RCA grey glass in my AtmaSphere M60s.   With no burn in, the Sophias were sweeter, smoother, and more detailed than the RCAs.  I find this remarkable gi...

Wig, thanks for the heads up on the Shuguang WE 6SN7s.  My M-60s  take a total of 8 6SN7s, which gets a bit painful at ~ $200/tube.  Fortunately, the tubes don't require matching and the amps seem to like a mixture of different tubes.  Right now I...

We are starting to hear some nice reports on these tubes.  I've toyed with the idea of giving a pair or two a try in my Atma-Sphere M60s.  Please keep us posted as they burn in. 
Tweeter Capacitor Upgrade (Coincident PREs)
@cal3713 ,  I think we are aligned with respect to our thinking on crossover parts selection in the Coincident Speaker family.  I just don't get it.   To pair the superb Accutron with a piece of junk in a 30K speaker to save $500 seams just weird.... 
Tweeter Capacitor Upgrade (Coincident PREs)
@cal3713,  I am happy you have found the Jupiters to your liking, and I agree completely with your comment regarding the manufacturer's choice of Solens for the PREs.   I know even the PREs are made to a price point, but I know in my case with the... 
Tweeter Capacitor Upgrade (Coincident PREs)
@charles1dad, I did not consider replacing the internal wiring.  I have used Coincident wire externally, and found it to compare well with a few other options in the same price range, so I didn't think it would be an experiment with a high probabi... 
Tweeter Capacitor Upgrade (Coincident PREs)
@cal3713 Another vote for the Jupiter Coppers in your application as a cap to be placed in series with the Accutron tweeter.   I used the Jupiter in my Coincident Super Victory II for that application with a Duelund Silver by-pass, and could not b... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
@atmasphere,"I don't use the word 'believe' because I made the measurements which showed that the power cord **without question** can affect the amplifier's performance. The measurement is easy- the voltage drop from one end of the power cord to t...
