Joe, try the Amperex out. I'm anxious to hear your impressions. Also, Victor gave me the go ahead to post his e-mail regarding phase:

Hello Sherod,

Many preamps and many amps reverse the polarity. This becomes a problem only when the preamp does, as Joseph's does, and the amp does not. This issue surfaced only recently when Cedar got a new amp and unlike his previous one, it did not reverse polarity. Joseph had never mentioned this matter to me before or I would have added it to the owner's manual and the specs.. I will be sending out a notice to all past customers on this matter when Joseph returns and sends me all their email addresses..

Sometimes the amp manufacturer indicates this fact and sometimes the manufacturer does not. I recently revised the owner's manual to note this fact and will add it to the specs in the ads shortly.

The simplest way to tell is to reverse the polarity of your two speakers. When a system is out of phase, the sound will appear a little flat; imaging will also wander rather than snap into focus. On most quality systems, it is not hard to tell. a minute's listening will disclose whether you are in or out of phase.

I suggest that you reverse the polarity of your speaker leads and see what happens: if the sound seems dull and less alive and imaging wanders or is ill-defined, then you are out of phase.

Best regards,

Victor
Joe, if you paid a premium for those Cca's, send them back to the dealer for a replacement or refund. I have read that tube dampers can sometimes over-damp a system.
Welcome Rob to the most exclusive pre amp club in town.Having said that, what "capable" pre amp did the AH replace.Thumbs up on Maggies.
Rx8man,

The Amperex Bugle Boy's are more full sounding with warmer mids and a larger soundstage. Just more musical to my ears and better suited for a digital system with any component that may be a tad HOT.

Sherod. Yes the fellow audiogoner is happy to take the cca's back. But thanks for the tip. Being new to tubes the variety of choices within just the Siemens and Amperex family, pricing, and policies for audition are a bit daunting. But I am just letting the learning curve happen while enjoying the music. My wife has never seen me taking the top on and off so much with a piece of equipment and she is intrigued (have to keep assuring her that it isn't broken and I havent lost my mind. lol)
Grannyring - thank you for the description of the Amperex. I think I will have to listen to some, given I have a fully ss system as well.
