Compare: Modwright LS 36.5 & Audio Research LS26

I'd appreciate opinions from anyone who has experience with these line stages. OK any comparisons including the Modwright and Ref 3 are also welcome.

Amps: Audio Research VM220 Mono Blocs (the Mono version of the VS110)
Wison Audio Sophias. Music: Classic Rock, Singer Songwriter, Classical, Small ensemble chamber, LOTS of vocals.

Recreation of stage & space, tube glow and midrange warmth and vocal realism, and rhythmic integrity top priorities. 80% vinyl, 20% digital.

Thanks for your assistance.
Jim

Rydenfan - Point taken. Which tubes are you running in your 36.5? I've only tried the stock 6h30's - are your using the supertube version and if so, is it worth the high cost? I did find replacing the rectifier with an NOS Mullard gave me some added resolution, but I haven't done much back and forth there.

You must replace the stock 6H30's with the 6H30 DR's! This is a no-brainer and will make a profound impact, especially in bass.

Interesting. As I understand it the DR's are the military-spec'd version of the 6H30 - can you elaborate on the differences between the stock version? Is there a difference in materials and or construction of the tube, or are they just culled from stock 6H30's using higher standards of tolerances? Which amp(s) are you using? I'm using Quicksilver 300B SET mono amps in a relatively small-midsize room in nearfield. Do you have a good resource for DR's? I know Conus sells'em.

Vett93 asked...

"The Modwright LS 36.5 uses only one pair of 6H30s in the signal path. However, it has both single-ended and balanced inputs. How do you do that with just one pair of tubes?"

Rather than using a dual differential circuit the 36.5 uses two Electraprint step down transformers to produce the balanced outputs.

Can you explain the differences between the standard dual differential ballanced circuit and the implimentation Dan
chose for the LS 36.5? Do other designers use the same approach?

Thanks,
Jim
