Mastersound Compact 845 preamp upgrade

No, no, no. My upgrade would be to put Mastersound preamp in my setup. Now I have only Compact 845 integrated amplifier. It has direct input, and with that input conected, becomes power amplifier.

I wonder, what would preamp do to my system...

I'm very very happy with my Mastersound Compact 845 sound. But every upgrade makes it even better. 

Oh, and the sound of Compact 845 is neutral all the way... 

Preamp arrived last week, and definitivly stays in my system!

What I got with preamplifier is lots of air, much bigger stage, and even more neutral sound presentation. Oh, and much more air. 

There’s no need for A/B test (with preamp or w/o preamp), with first tone everything becomes so obvious...

Pure music enjoy!
