Theoretically, the max output of the HD900/5 at 1 ohm is 75W and that of the HD600/4 at 4 ohm 150W, so the fronts should be a lot louder, but they are not. I'm not worried about it though since I can raise the gains on the front channels to compensate.
The "low/High" input switch discussion though has got me thinking. I've had a problem with noise on the HD900/5 amp. When I switch from low to high, the noise goes away but of course the output level gets reduced and of I raise the gain to compensate, the noise comes right back. I was thinking, since the MS-8's speaker level outputs are of very good quality, what if I used those instead of the low level RCAs? Any potential downsides to doing that? This may be a good solution since it would kill 2 birds with one stone - getting rid of the engine noise AND utilizing the reportedly superior input option on the HD amps.

Why is the high level input, reportedly superior. |
Sorry, just saw this now. Honestly I don't remember why I said that!
