Joe: I had never used the tubes except to check that both sides were working when I received them (I purchased 10-12 of these and only used one or two in my previous Audion amp). I had mentioned to the previous user that they needed a mininmum of 25-35 hours for the bass to kick in (don't know if he ran them this long). A "rougher" sounding (but good) 6922 type tube is the older Mullard. I do not have any matched pairs on hand, just singles. If you don't end up using the 7308's, send them back my way as they are half of a matched quad that I may find use for in the future. As far as the Cary goes, I have not heard it, but have never been a Cary fan in the past (with the exception of a power amp that they had years ago that sounded like an AR modified Dynaco Stereo 70). I also prefer a somewhat blurred presentaion, which sounds more like live music to me.
Integrated Shootout: Rogue Tempest/Cary Sli80 sig
The Cary is stock re: all tubes except power tubes, the 6922 tubes are Sovtek, the 5u4g tubes are Sovtek as well, the 6sn7 tubes are Chinese, and the power tubes are Svet 6550 and Electro Harmonix 6550EH.
The Rogue has the Sovtek 12ax7 and JAN Phillips 12au7(tube upgrade from Rogue) and the same power tubes (Svet 6550, EH 6550EH).
Ok. The Cary is a bit more refined. Alot, actually. But the Cary with stock tubes, is brighter (I can't believe I think it sounds bright, but it does).
The Rogue had soundstage DEPTH out the yin-yang, while the Cary is more 2-D (I don't like this at all).
As far as Soundstage width , the Cary is wider, but with the depth lacking so, it seems more "fake" than the Rogue.
The Rogue, because of it's depth and acceptable width, sounds more like music in real space, but with a more "tubey" sound (it sounds colored, but the coloring makes it sound real), while the Cary's tone is purer and the pace more lively, but because of the brightness and flat soundstage, it seems to suffer by comparison. Both throw an image very, very well.
I am going to be tweaking around with some 6sn7 and 6922 tubes for the Cary, in an effort to get the brightness out (I know this can be fixed) and most importantly, the soundstage depth up to snuff. I just wanted to post my results so far. The Tempest, with the upgraded preamp tubes from Rogue (I think a $100 option) gets the nod vs the totally stock Sli80.
This is going to get good.... stay tuned.
Opinions are appreciated...
