Need a new amplifier. Need a good match for my Audio Research LS7 preamp


Speakers - B&W CDM-7NT

NAD CD Player

10x12 room

SS or Tube, New, or used.  Looking to tame a little top end brightness, and more clarity at higher volume.

Mostly Classic Rock, Reggae, Singer songwriter stuff, with a smattering of Jazz and Bluegrass.  Lots of ground to cover. 

Current amp was an Arcam Alpha 10 100wpc.

Looking to spend around $1500.

Saw a used Odyssey Khartago Extreme for under $1k, but don't know much about it, other than needs to be biased to your homes electric output, and had some real good reviews. Sounds a little finicky.

Appreciate your input

I believe the amp Ralph (atmasphere) was referring to is the Music Reference RM-200. In it’s current Mk.2 form it retails for $7995, and can very occasionally be found used (it’s a keeper!) for around $3000. The original non-Mk.2 version goes for $2000 or so. Nice amp, which Michael Fremer reviewed in Stereophile a few years ago, putting it in it’s Class-A Tube Amp category recommended components list. Heed hansk46's advice regarding input and output impedances---the RM200 is XLR/balanced inputs only, at 30kHz ohms.

I have Khartago Extreme and it's awesome and a great value. Great match too
Spoke with Klaus at Odyssey, and am going with a Khartago Extreme.
Pricing about the same as a lot of the recommendations.  
A new amp vs a 7-10 yr old amp.  Also gives me the option to convert to a monoblock and get another. Or just upgrade the amp even further.
Plus a 20 yr warranty??? Seems like a no brainier
Will follow up with a review.  Thanks.  After that, may see what a DAC does for the overall sound improvement
