Siemens CCa vs. Amperex PW 6922

This has been a subject(the original posting question)that has interested me for years!Yet,even with all these responses,I feel I still am in the dark regarding which is ultimately the better tube(all things being equal).

I've had good success with Amperex 7308,Ediswan 6922's(CV 5358 and 2492),and now some primo CCa's( I keep the CCa's in my phonostage as of now)....The older dreck I've tried,I won't even mention.

My friend(with almost identical equip)has gotten ripped off with dreck Teles,and we were both underwhelmed with the low noise/good testing Mullards we tried.He also has superb Amperex 6922 PQ U.S.,which I think we should A/B against his current fav,the CCa's.Might be interesting,now that he's made equip changes.

BUT....


Back to the original post question....I wish these were some folks who could "reliably" make the "comparison" of the CCa's against the PW's!

I now live with superb CCa's,but the "aura" of the PW does exist,and there really does NOT seem to be a reliable comparison,other than Joe's Tube Lore(a fun read)who uses a digital based system for his opinions!

In my case,I have a three tube phonostage,and am always wondering if I could get more with a nice threesome(I know where some are,but very expensive)of PW's,if I was to switch from the current CCa residents.

Mine are very quiet and I like them,but the reputation of the PW still fascinates me.

Btw,I have six(two additional/seperate back-up sets for my phonostage)very low noise Ediswan 6922's purchased years ago from Upscale Audio(before you "HAD" to buy equip too,in order to buy tubes).They are very good substitutes for my CCa's,and I keep them in case my 10,000 hr(supposedly) tubes go down.The Ediswan's I have are quite good."PLatinum Series" with much better low-noise numbers that Upscale Audio has been selling in the last few years.One reason I keep them.

Yet,I DO wish there was more feedback regarding the CCa vs PW,based on BOTH being in tip top shape,and just comparing the characteristics of sound!

Guess we'll never know -:)

Tvad,well I don't know why you seem to be ruffled by my comments.It is not to criticise anyone.But you do appear to be irritated.Sorry!

I still don't see anyone(including you)who has made any thorough,or meaningful comparisons.Enough good input,to make someone spend the kind of money these tubes command.

You basically say, "they are both microphonic,and you would stay away from both".But,you prefer the PW's.

Sorry,but that just is not much of a comparison,and I am not trying to be a smart-ass!It is just not much to go by.

Hence my comments,which basically was meant as a lament,for the lack of "enough feedback"(besides the "I like A vs B" one liners,which seems to be the extent of info on the subject).

At the asking price of NOS PW's,for an individual to find out for themselves,I was hoping to see a bit more.....That's it!Why so peeved?

So I stand by my comments which "only" reflect my remorse,for the lack of meaningful input!

Nothing personal!

I made comments in another thread about these tubes, which frankly I
mistakenly thought I made here, and then realized you likely hadn't read.
Therefore, I deleted my post above.

Tvad,no problem....

Since I may be interested in pulling the trigger on a pricey threesome of PW's could you "please" give some descriptive/comparative input?

I'd really be interested in your comments!

Best

There are some good comments from several members in this thread.

If you have any experience with German cars, I would characterize the
Siemens CCa as Porsche 911, and Amperex PW 6922 as BMW 540i. Both are fast and precise. The BMW has a certain suppleness that ever-so-slightly smooths rough roads while still providing the driver with excellent road response, while the Porsche transmits the road surface untouched.

Both tubes create very a large image size IMO, larger than any other tube in
the 6DJ8/6922/7308 family, and each takes treble response right up to the
line of being "too much of a good thing" without crossing over the edge. It's
this treble extension that provides the outstanding spatial cues. I believe the
CCa can be too exacting at times, whereas the Amperex are generally more
forgiving...but this is just my opinion in my system.
