Conrad Johnson amps: premier 12, premier 8,LP275M


I actualy own a pair of CJ premier 12 wich i like very much matched with a Premier 16 LS 2 (preamp).
I am looking for a bit more authorithy and power especialy in the lower octaves...
so my question is how would a pair of CJ Premier 8 will perform in the bottom end compare to the Premier 12?
Also an another choice will be the newer LP 275 M (CJ)?
Any reliabilty issue with this generation?
will the famous house sound (lush) be lost in this newer generation?
i want to stay with the CJ family and my speakers are the (easy to drive) PARSIFAL OVATION by Verity Audio.
Any opinion on that match is welcome!!!
Is 275 WPC will be overkill with these speakers?

I had the Parsifal Encores, driven by a pair of Prem 8's
back in say the mid 90's. Pre was 16ls and then Art, both
series 1's. The Parsifal to me is a fairly easy load, in
comparison with the usual suspects such as Thiel,Avalon..
I felt that the 8's were adequate in power, but I would
not have wanted to live with any less. I actually at times
felt that I wanted more. I think that what I really was
was looking for was a more controlled bass, w/ better
articulation. I steal Tim's descriptions of what the 8/12
series lacked in comparison to the newer CJ, which I have
no experience with. I did try a Class A Accuphase amp,
which did have much better bass control than the 8. I kept
the 8 and sold the Accuphase though. I preferred the CJ
in the mid/upper frequencies. IMO, I would try and get my
hands on an LPM 140, and see how you like it. If its the ticket but you want more power, get the big 275. You may
want to also consider a VTL 750. I run them in Triode w/
350 watts, plenty for my Vandersteen 5A's. Nice system,
what is your source/sources and cabling.
I am using CJ Premier 12's with a Modwright 9.0SE preamp and Gallo Ref3 speakers. I was also looking for a bit more low-end power. What is working for me really well now is to add a REL Storm subwoofer driven by the speaker-level outputs of the CJ Prem 12's. Importantly, I have the low-pass filter on the REL turned all the way down (begins rolling off at 22 Hz). Also, I have the REL positioned in the near-field (much closer to the listening position than the main speakers). I am VERY happy with this set up. The bass is strong, fast and well integrated. The glorious sound of the CJ's comes through unpolluted.
source is a CEC TL 0 + a JADIS JS1 CONVERTER and all the cables are by NIRVANA SX LTD.
Actually more looking on an hybrid amp (best of both world)
the famous house sound has been gone for several years. the last great amp was the cj mv 125. i have been looking for one for a while. i have heard this amp drive a pair of magnepans.
the classic romantic sound with a premier 12 is mostly gone when tubed with chryo kt 120s instead of stock regular 6550c's. regular kt 120s are about one third of the change.
