tube amp help CJ,VAC, or VTL


I would like to upgrade my Adcom amp and would like to try out a tube unit. Considering CJ11A,VAC100, or maybe VTL. What are the characteristics of the different amps and how much improvement can I expect? I will be using an Audible L1 preamp and Spica TC60's. Suggestions?

Listen for yourself and decide. In my estimation you will not get better "sound" and build quality for the money than Conrad Johnson can provide. I adore my Premier 11a in all aspects. I upgraded from a Hafler 500 and feel that it was a "big" improvement. If you can compare tube amps in your area, do so. I have never heard VAC, but understand it is great gear. So listen to all of the makers if you can. My premier 11a drives my Martin Logan ReQuests to fairly loud levels with no problems. Happy listening!
I was in a very similar situation to yours; I had an Arcam Alpha 9CPre-Am coupled to an Alpha 10 Power Amp. While I enjoyed the sound, it just wasn't as "sweet" as I would've liked...specifically at low volumes...while the "punch" was there, something was missing. I started looking at tube units: VAC, VTL, C-J, Audio Research, & BAT. Dealers and friends began to caution me..."You don't want tube equip...too much hassle, etc,etc, etc..." I happened into a VTL 2.5 Tube Pre-Amp coupled to an Aronov LS 960 Tube Power Amp and let me tell you...what a difference. I understand why tube gear has such a loyal following...tubes sound fantastic!! While the VTL projects a large, airy and detailed soundstage; the Aronov is truly a GREAT amp!! You will be hard pressed to find another pure tube amp that sounds as good...even more hard pressed to find one with such a "muscular" presentation on the low end for 3 times its price. I waswarnedthat "tubes don't have the low end or punch of solid state,"...not so with the Aronov. If you want to get into really good tube gear without spending a fortune, check out Aronov Audio!
I have owned many tube amps, CJ ARC and VTL. I currently have Melos monoblocks and personally prefer them. The powersupply provides a lot of punch and the triode circuit is smooth and open without being as romantic as the CJ sound. However, if you can't decide I would go with tubegroover and buy ARC you won't be unhappy particularly with a VT 100 or 200
Audio advisor have a great deal on pair of VAC monoblocks. if you can afford 2K...they were 6999$ originaly.
Try the VTL ST 85. VTL amps seem to retain many of the good qualities of solid state, and give you all the advantages of tubes. LISTEN AND COMPARE IN YOUR OWN SYSTEM BEFORE YOU BUY, THOUGH...
