I've had a Digi-Buss and Buss-Stop for a few months now. The former has one Pass & Seymour 5362, one Furutech GTX Rhodium and one Furu GTX Gold. The latter has one Pass & Seymour 5362, one Furutech GTX Gold and one Furu FPX Gold.
Into the Digi-Buss are my Mac Mini, external HD, Uptone Regen, AR-T Legato and DAC. The Digi-Buss, and my amp during lightning season, are plugged into the Buss-Stop.
The Buss-Stop, like the Mini-Buss I had previously, does an excellent job of passing through power without degrading the sound in any significant way. There is just a slight diminution of macro-dynamics - with my amp only - which requires attentive listening to hear.
Although I have a whole house surge protector, the additional protection from external surges (I live in the lightning capitol of the country) as well as the protection from internal surges (refrigerator, washing machine, etc.) - especially for my computer gear - makes the Buss-Stop well worth the expense to me.
The Digi-Buss, on the other hand, reduces the noise level, provides more resolution, and actually increases both macro and micro dynamics. Again, well worth it for me.
