Amp Upgrade - 3k to 4k used?


Hi Folks:
I’m thinking of upgrading my amps and would value some advice. I currently have Blue Circle BC2 Monos. I’ve been really happy with them, but the upgrade bug is starting to bite again. I could spend about $3k to $4k on the used market. I’m particularly keen on tube amps (especially low powered SET), but not sure if my speakers would be efficient enough. I know my CD player is a little old too, but don’t think an upgrade here will get me a big bang for the buck. I’ll also consider upgrading IC and SC as well a little later on, but want really really good stuff (FIM or Valhalla likely). Another option may be to get a Shunyata Hydra. The rest of my system is:

Audio Physic Virgo II (89Db efficiency, I think)
Sonic Frontiers Line III – (but expecting delivery of Supratek Chardonnay in a month or so).
YBA CD 1a
Nordost SPM IC & OTA Sakura IC
OTA Sakura Speaker Cable
3 Shunyata Sidewinder Power Cords, 2 YBA Diamond Power Cords, 1 pair of Bybee IC Filters, FIM outlets.

All advice and recommendations welcome. Thanks,
John.

Try the Classe CA-201 or CA-301. These amplifiers are musical, dimensional, transparent have row upon row of layering and the uncanny ability to flesh-out varying instrument and vocal tones/color like the real thing. Great staging --depth, height and width. Fully balanced (works great with SF pre's --particularly the Line-3), also SE inputs, bridgeable, gobs of current and simply does not lose control with virtually any speaker or at any volume level --it always remains musical, composed and focused. A great bargain and built to a very high quality --inside and out. You won't be disappointed.

John, you might consider the Rowland 112. i know it is solid state but i owned one for 6 months and was very impressed by the top to bottom musicality and lack of ss etch.

i am a tube guy (Tenor 75Wp monoblocks) so that is where my heart is but at $3k to $4k used it is hard to beat the overall performance of the Rowland 112.

it doesn't hurt that the Rowland is a built like a tank and is one of the more beautiful amps out there. the older 112s have the polished case (like the #10 and #12) but the newer 112s have a cheaper black case....so try to find one of the earlier models (it was costing Rowland too much to use that polished case for an amp in that price range).
Thanks for all the advice guys - some very good amp options mentioned - good food for thought. Cheers,
John.
