My Dream system is finally complete. I have been building this system over the last few years. My two channel system is done for now. Starting on the Theater system next!
Ditto the Great system. I own Mc and it looks like your on the right track and know about system vibration. One of the pic's shows something that looks like foam under the feet of the disc player. That will 'muddy' the sound more. The best way IMO to drain the internal vibrations is to put some brass footers under the components coupled to a maple plinth. Listen every day.
The only thing I would Change is ...trade in the c-15 and the 831 . You might like the sound better by using an MC301 direct to the amplifier! the 301 has an awesome transport and a volume control! I have a 352 and a Mc201 + Mac tends to be pretty warm unless you brighten things up a little with some good Nordost cables ! Love your system.
