Siemens CCa vs. Amperex PW 6922

Of all the Amperex tube variants (6DJ8, 6922, 7308), I always preferred the Amperex 6922 PQ USA White Shield. I thought they sounded very, very close to the 6922 Pinch Waist, and without the astronomical pricing and dicey microphonics issue that plagues the Pinch Waist tubes and makes good ones so difficult to find.

Andy's the best in the business. Period. However, he does have a negative opinion of Siemens CCa tubes, primarily because he has found many that have not measured up to his quality control criteria. Remember I wrote that many CCa are microphonic?

Even one of the CCa tubes I purchased from the German gentleman mentioned above was microphonic and required shipping back to Germany for an exchange.

Tvad,

Brent Jessee has a matched pair for $225.00. I guess I will flip the switch and go for it.

The last pair of this type tube I got off of EBay and they were bad.

Brent is easy to talk to and has a 30 day return policy.

I had a pair of Seimans CCa DS and I sold them for $300.00. Hello McFly.

Andy thinks the people that know about the older CCa's are nuts because all he has to sell are the later ear-hair-burning versions. Not hard to figure out: Ignorance is bliss, and profitable too. Enjoy whatever you settle on.

99999999,

I am using E81CC Mullard/Valvo '66 & CBS 7728 in the Lector T7 MK3. For digital it is, at times, good sounding

When I was running the Lector for two weeks because of changes in my vinyl setup I really did think it was sounding GREAT. Boy was I deceived as I saw the light when I got the TT back up and running.

He that has ears to hear let him hear what the analogphiles have to say. And some having ears to hear hear not.

You have A..Y pegged.

At least you're at the top of the digital ladder. No doubt about analog(done right)though. I SO miss the days when direct-to-discs, original master/virgin vinyl, 1/2 speed mastered, MFSL, Sheffield, Crystal Clear, TELARC, JVC Soundstream, Nautilus, CBS Masterworks, ET AL were inexpensive and plentiful. Technology does march backwards at times doesn't it?
