Yeah, I don;t quite remember how I stumbled onto that site, but I can tell you that after seeing Cary and others at my local HiFi store I was really astonished at the prices.
I was very nervous about the DIY aspect of it at first, but the preamp looked like a neat project and for 150 bucks...
Yeah, buy an amp that comes with a turntable and vinyl! :)
Just kidding....but only a little
But seriously, no. You do not need to purchase any special amps to listen to your SACD player. A two channel amp of the same manufacturer will sound the same as the 5 channel version...
