Compare: Modwright LS 36.5 & Audio Research LS26

Jax2,

I guess i see where you are coming from. My excitement for my RWA system and my past posts about it sound like i am a "shill" to you because this is what ive been posting about since I joined here on Agon. Look, I don't need to be on RWA payroll because I've already been "paid" with much enjoyment from listening to my system everyday. I have no special relation with Vinnie and RWA. I paid full price and am glad to support 'em and will continue to do so. I was not asked to post anything here or anywhere. If I want to show my excitment and post about it here or anywhere else, I am allowed to do it and anyone can view my past posts and I hope they will. I'm not trying to thread-jack or start a pissing contest or anything. I saw the original post and what Jdolgin was looking for and it sounds like he would really like the sound of the RWA Isabella preamp based on his description so I posted to him about it. It is somewhere in the price range he is looking at i think so i thought he might find it a helpful recommendation and there are plenty of others out there too. if not, no problem and i meant no disrespect to him, you or anyone else.

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.
