My two channel system is Merlin TSM-MXr and Manley Stingray II tube amp....fairly pricey amp when you price it out by the watt!
But for my large home theater I have 3 Emotiva Amps and the UMC-1 proccessor. The amps replaced gear from Rotel and Parasound, but I also compared them to a modified Odyssey stratos. I've reviewed their stuff elsewhere, but let me just say that the Emotiva amps are amazing for their cost, especially when used in home theater systems.
Now...compared to my Manley tube amp the Emotiva XPA-2 suffers a big loss, especially in soundstaging, but then the Manley costs 10 times the price!
Also: I waited for the bugs to get worked out of the UMC-1 processor and it's been a fantastic unit. It's also superior to my Onkyo that also cost me 4 times more. So again...for HT use, very hard to beat the value of the Emotiva stuff.
Cheers,
Rob
