I had a SF line 1, Classe 200, SF CD player and B&W 802 series lll in my 28 x 17 living room for two years. Classe makes excellent amps but I am not as impressed with their other gear. Went to B&W 802N, and a little bass power was missing. Now have Classe 401. Got a deal on Leavinson 380S and sold the SF line 1 after that. Point being... The first system was very good, the second is more expensive and EXCELLENT. I really did like the tube preamp....but the Levinson is hard to beat if you can afford it.
Classe vs. Sonic Frontiers
I currently own a Classe 5 Pre and power combo. I am wondering if changing the pre to a Sonic Frontiers Line 1 or greater would be a huge improvement. Also would be interested in the phono 1 to replace the internal phono in the Classe. If anyone has experience using Sonic and Classe let me know what your findings are. I am powering Proac speakers with this setup.
