I preferred the Luxman M800 bridged on all counts over the Ypsilon hybrids in a direct shootout on Vivid G1. The owner Joel might marginally prefer the other way but loves both. The Luxman also drove more effortlessly. Very organic and full bodied. Since you are in India, you can pick them up from Hong Kong at 230v cheap. The M800 has now been discontinued, and you have the M900, which was much better than the Viola Symphony on TADs Evolution 1 floorstanders. You can if you require, stagger your budget to buy another one later to bridge and create monoblocks. One reviewer rated it as the best amp he had heard (maybe hyperbole, just saying). If you check with M800 users, a lot of them have toyed with the "valve or Luxman" question. Extremely well engineered and solid.
