Modwright LS100 VS Modwright LS36.5

I have the LS100 with Black Treasure 6sn7s and a Philips 5ar4 and echo Wilysnet's comment about it. I asked Dan Wright about the difference in sound between the 2 and he said that the LS36.5 was faster due to the 6H30.

I'd go with the LS-100. The highly resolved, ever so slightly warm (for a solid state amp that is) and inner detail and micro-dynamic finesse of the Pass amplifier would be complemented well by the richer texture of the LS-100. Personally, I think a 6H30 preamp here would be a bit boring.

I know a lot of people aim for absolute neutrality, but you know, one person's neutral is someone else's cold fish. Fortunately, I think a Harbeth owner would appreciate that sentiment.

When I had the LS-100, it was outfitted with Sophia Electric 6SN7 tubes and Mullard 5AR4 rectifier.

I presently own the Atma-sphere MP-3, which I think is slightly more neutral but just as beautiful.

Best 6SN7 preamplifier I've heard is the TRL Dude. I owned one briefly, but its chassis was too large to be suitable in my shared listening room. That might not be a problem for you.

As for DACs, I think one of the best values out there right now is the NAD M51. I'm really impressed with it, and having been through many DACs over the years, I can say this one is a real standout. At least it is in the $1500 - $3000 range.

I've owned both and prefer the LS100 which in my system produced deeper bass and more body. The LS36.5 is a tad quieter but leaner throughout. Both are excellent (outperforming my ARC LS26 easily)and your decision is really one of system matching. If you want to add just a touch of warmth then the LS100, if you want a more neutral presentation then the LS36.5. I also like that you can tube roll with the LS100 and the built in headphone amp is excellent and certainly nice to have. Finally, you can always add Dan's excellent DAC or phonostage to the LS100 which is not possible with the LS36.5. Given the entire package the LS100 has to be one of the best bargains out there at the moment.

That's right, it's very difficult to tube roll the 36.5. There are only three choices for the 6H30. Two new production manufacturers which are sonically nearly indistinguishable, and the very expensive DR version which is NOS. The DR version is more of a good thing, but in terms of character, pretty much the same.

Clarrie, if you get the LS100 just make sure that you give it the 4-500 hours of break-in that Dan recommends to really hear what it sounds like
