Modwright SWL 9.0SE Preamplifier


I happened upon this and if the reviews are anything to go buy this is one heck of a pre. Seems the price goes up very shortly so I may want to snag one before it does. I was wondering if the house had any experience? Also to what kit do you used the pre? I was also looking for tube monos to compliment it.

Many thanks :)

Thanks for the tip. I thought it wouldn't be so straight forward because my setup includes a REL subwoofer (which connects to speaker ground and right/left speaker terminals), but of course the sub has a phase reversal switch. So it should work as you described.
Unsound is unwrong. Yep, that's all you do...reverse blacks and reds at the amp (or speakers, not both). Remember, inverting phase doesn't mean out of phase (where one speaker is wired wrong and mono signals lose specific image). Theory also says that so many multitracks and so many microphones are being used in most recordings that some of them are inverted anyway.....
Seneca it is more sonically advantageous to have a circuit that inverts phase because it is a simpler circuit requiring more attention to circuit design. On the other hand a circuit that does not invert phase has extra sound-degrading circuitry. Many quality preamps for this reason do invert phase.
Dan Wright tells me that inverting phase is a natural consequence of a more purist (straight wire with gain) type of implementation with tubes stages. Dunno....lots of tube preamps do I guess. I believe Dan feels that an invert phase switch adds unnecessary switching/noise in the signal path. No big deal, really.
