I currently run Rogue M-150's direct from an ML 390s. Absolutely no problems. I ab'ed it against several preamps and the bottom line is you will have to spend a bunch to better the quality of the volume control in the 390s, particularly if you run a balanced connection from the 390s to the amp.
Run direct from ML 390s CD player without preamp?
I was considering running the Mark Levinson 390s CD player/processor direct ly into the Conrad Johnson Premier 140 power amp with the Wilson WP7s. How would that work out? What are the advantages or disadvantages of leaving the preamp out of the system? I do not need a tuner and plan only to use CD in the front end.
