I own the SWL 9.0SE (one of the first production units). I'm a big Dan Wright fan, also owning his Modwright 3910 Signature universal player, and previously the modded out 999ES Platinum Signature. His work is genius and relatively inexpensive. In the world of $2k preamps his is a marvel. The tube "sound" is there, but only in that it is a very analog (not overly warm, just perfect) crystal clear picture window into any recording you put through it. Soundstage and detail are state of the art. Tube rolling is somewhat an option, but I've learned to stick with the Tung Sols or Jan Phillips that Dan espouses. I tried Hal-O hi-heat tube dampers for awhile but frankly like the pre without them. The newest BlackSands Violet PC sounds incredible with it. The SWL has a remote volume control, and has an HT bypass (I'm proud to say I pushed that feature and Dan complied) that proves invaluable in my home theater and 2 channels setup, keeping the signal paths separate. The only thing I wish it had was a phase switch (it inverts phase normally). Dan's work is incredible, and his customer support and willingness to go the extra mile are the main reasons I will always have a "Modwright wins all ties" attitude. Next up, his production release of his phono stage, available both stand-alone or internal to the preamp.
