I've been talking with several people today on eBay about the C-19 and it was even brought up here, which got me to drag it down to my main system along with the TFM-45 & 490t for some more critical listening time. I'm currently running a Melody SP 7, a 45 wpc fully tubed integrated so this was a quick swap and comparison. The Carver stack comes up a little short on the 3-D imaging but seems to excel with just about everything else. The C-19 and TFM-45 is a beautiful match up, they seem like they were born together, very natural sound and the power of that amp is what got me into high end audio in the first place. The C-19 is a fantastic preamp and has me now reconsidering the whole integrated route. I bought a Jolida 502Brc with KT88 tubes, it should be here early next week and I think I'll wait till it arrives for another comparison before I sell the C-19.
