Shelter 7000 load capacitance
I am using 30 ohms after quite a bit of experimentation. It sounds great! 
Schroder sq and the new talea
Hi Mikelavigne,I had exactly the same impressions. And so did two others that I was with in the room. I think the differences were pretty obvious. That being said, I have no idea what was the greatest contributing factor. I am wondering about the ... 
Schroder sq and the new talea
Granted that it was impossible to distinguish the effect of the tonearms in this comparison. But one thing was clear to me - the Talea setup outperformed the Schroder setup by a significant margin. Joel Durand played a piece by Ravel that floored ... 
Cayin A50t biasing problem
Here is another suggestion - since I just blew a fuse in my VP-100i. DON'T stick the common (ground) probe in the well on the same side of the amp as the hot probe. Use the common on the opposite side of the amp. That way you won't have to trim th... 
Cayin A50t biasing problem
Are you sure that your probes are touching the bottom of the bias test insertion points? On my amp the insertion points are quite close together. The probes get in way of each other and didn't reach to the bottom until I cut away some of the plast... 
6922 not 6H30 Based CD Palyer
I just got a Cayin SCD-50T. It uses two 6922s and a 12au7. I am using some Soviet NOS 6922s and a Mullard long plate 12au7 (or Telefunken smooth plate). I like the Soviet tubes a bit more than Amperex PQ's in this piece. The stock EH tubes do not ... 
Cayin A70T has bogus tube rectification?
I am not asking you to trust the findings of me and captkhz. Check the thread on PinoyDVD for what we hashed out so that it doesn't have to be dealt with again in this thread. We have no agenda other than to alert other to this stuff to that they ... 
Cayin A70T has bogus tube rectification?
Al, you are thinking the same thoughts we had. We had been giving them the benefit of the doubt as to having made a design mistake and then tried to cover it up. But you would have to be pretty stupid to inadequately design the rectification circu... 
Cayin A70T has bogus tube rectification?
No, Cayin is mis-representing their products if (and at this point I don't think there is much doubt) our findings are correct. How cynical do you have to be to "fake" a feature? I don't care if the amp sounds like the highest seraphim cherubim, t... 
Cayin A70T has bogus tube rectification?
Good suggestion and already done. The Cayin seems to have excellent output transformers so it is worth fixing up. My amp was apparently mis-manufactured. We saw 5%-10% harmonic crossover distortion at 10W output. The biasing was so crazy we never ...
