Nice setup. I still have the 27.5, but my son has the B&Ws. If you know how to solder, bypassing any electrolytic capacitors in series with the drivers with say ODAM caps won't kill the house sound of the 801Ms, but it will open them up, and the house sound will be diminished. Granted, the house sound is seductive as heck, but it's not gone, and you'll almost certainly love the improvements. If you really want to nail it, get a DS2 preamp before Don Sachs stops making them, he's semi retired now, and the best Lampizator DAC. Don't buy the DS2 used as he has made important upgrades lately, the Lampizator due to supply and other issues I would buy used, but only ones made after 2020. If you get a Lampizator, I intend to bypass the splendid o/p caps with ODAM and V-Caps, so let me know and I'll tell you if it's worth it. I won't go into what I replaced, but 2 very well reviewed, and actually impressive DACs were slaughtered by an inexpensive, relatively speaking, Amber 3, unmodified but with a very expensive Maxda cap in the output.
