Siemens CCa vs. Amperex PW 6922


Audio Note 300B amp with Dodd battery preamp and ASR Exclusive.

Has anyone had both at the same time and have some insight on which one would work with my system.

The Amperex PW seems high in price vs. the Siemens CCa GP.

Dvad,do you like the Amperex 6922 PQ USA White Label better than a very good set of CCa's?

Chatta,

Have you had the experence with both tubes in your system to say that the Amperex is better?
I wonder why no one has mentioned the Siemens E188CC/7308 as an alternative. The high end is just slightly relaxed(ala the PW), but the tube still retains the liquid/3D midrange of the CCa. A slightly more controlled bottom(but no loss of extension)compared to the PW. I've a pair of these as my "back-ups".
I agree the E188CC is a great alternative to the CCa. I also quite liked the
Siemens ECC88, which is theoretically at the bottom rung of the family of
tubes,
but I liked the slightly warmer tonality of the midrange.

Either the Siemens E188CC or the ECC88 are great alternatives, and they and
be
found at prices substantially lower than the CCa. They just don't produce the
hyper real image size of the CCa.

However, I still prefer Amperex 6922 PQ USA White label to either of
these...since I prefer the Amperex house sound overall.

IMO, FWIW, Kumbaya...
