does anyone have any experience or advice on Emotiva products? i am researching an entry level integrated amp. i looked at the CA Azur 550, the Marantz 5004, and the NAD 316beee. I have been advised that as a first timer getting into Hifi, Nad would be a Great start. but in my research, i came across a company called Emotiva. they are offering their Usp-1 and Upa-2 for just over 600.00. Most of my music is digital and Emotiva has a Xda-1 which is basically a dac/preamp thingamajig? Anyway, my question is, as someone on a limited budget who want to break into Hifi, is Emotiva a way to do this? Are Emotiva products decent? and does anyone know if you can use the Xda-1 as a preamp with the Upa-2 amp as a computer based stereo? thanx.
