Audio Research LS2

Lourens · 2nd April 2004, 07:49 AM

Hi
I want to modify my Audio Research LS mkII pre amp. I already swapped the Sovtek tube for a Russian 6H23N-EB and fitted a Furutech IEC AC inlet, both about a year ago. It is 9 years old, and was last serviced and updated by the Dutch distributor in 2000 (the first Sovtek replacement and extra shielding).

I like the sound of this amp very much, but I know there is a lack of transparency, dynamics and punch, compared with some other great pre-amps. Still I preferred the LS2, because of its warmth, staging and ease (using it with my Spectral DMA-150 and Kharma Ceramique CE-1).

Can anyone tell me what’s the best way to go? Or point me the way to other experts or sources (the only one I found on the web was Great Northern Sound, but I definitely prefer diy).

Thanks!
Lourens

OK, replacing elco's and rewiring seems a good idea.
A schematic or service manual should be helpful to identify crititical components, I guess.

Any hints or second opinions from other forum members on this?

TIA
