Thank you for the feedback Arjun.
My current amp is Yamaha 475 connected to Bookshelves from my older Aiwa HT setup.
My usage is 80% music and 20% movies. I had auditioned Tsi400 at ProFX with Denon Amp (I believe it was 1612) and I found it a major upgrade in terms of SQ.
Being a newbie here, is there any other way I could contact you since I am not entitled to PMs.
