Well for a couple of months I had been waiting for the upgrades for current Momentum pre-amps to HD level to begin. My dealer had called about a week and a half ago to say they were ready to ship my in. After some discussion I decided to skip the upgrade and just purchase a new black unit to match my M-400's. I like the updated styling of the HD version which is more in line with the amps.
I have been listening with my current pre-amp out of my set-up for over a week now. I have connected the Vivaldi direct to my M-400's and I have been happily surprised at how good it sounds. Maybe I don't need the pre at all.
