Upgrading from Adcom GFA 5802

Hi everyone. I'm a long time reader, first time poster and would like your opinions for a new amp. I mostly listen to prog rock Genesis, Yes, etc. I have the matching preamp, big energy speakers, good cables, etc. I like the overall sound of the 5802, especially the base, but the high end seems rolled off and I would like more transparency. My dealer suggested the Krell KAV 250, which made sense. However, it sounded too controlled almost mechanical in my system. Next, I tried a pair of BAT VK-200 monoblocks. Transparency and highend extension in spades. But not enough low range punch-for prog rock anyway. Now I don't know what to do. If any of you have had a similar experience, I would really appreciate your help. Thanks, Matt.......

I used bryston 7b st mono blocks on my b minors,for about 9 years with great success,and yes the b-minors can handle the 500 watt power output of the amps,they can drive the amps to clipping if pushed with no strain from the skrs.

Y9,
If you live near Madison, WI, I have a 5802 with John Hillig's platinum mods. Might be fun to compare to your stock 5802 if you're in the neighborhood.

Hi Yes9,

I used to own two Adcom 555 MkII amps, bridged to monoblock mode to power my Snell B Minor speakers. I tried the Bryston amps, mentioned above, but thought they sounded cold. I eventually decided upon Plinius equipment, and have been very pleased with it. I use their integrated amp. Great detail and extension, but also warm and life-like. If interested, please e-mail me. I might know someone who would let you demo. (No, I'm not a dealer or connected to Plinius in any way).

Best regards,
Paul Frumkin

Contact John Hillig at:

www.musicalconcepts.com

He offers a series of reasonably-priced mods to your amp. I did "mini-platinum" mods to an Adcom amp about five years ago and was most satisfied. Throw $800 to $1200 into a Nelson Pass designed amp for primo parts (Black Gate caps, tantalum resistors high speed diodes) from a guy who knows his stuff and you'll really have something. Resale on the stock 5802 won't get much of a downpayment on another brand.

Best wishes,

jb

If I were you, I would try the Parasound Halo JC-1's.
These match up extremely well with the Adcom GFP-750 preamp.
Plenty of transparency and top-end extension, along with outstanding bass control and extension.

Any of the Pass labs X-series amps will give you what you're looking for.
