when the Evo4 is run in bridged mode you have double the Evo2 processing power, 2 tripath chips in place of the one in the Evo2... my understanding is that each doubling of a processor results in a 3db reduction of "computation noise"... Accuphase used to have a brute force implementation where they had something like 8 (or was it 16) Burr brown DAC chips per channel... with the right preamp you could, potentially, run an Evo4 as a monoblock with a hyper bridged configuration and gain an extra 3 db in the process.Another thing to consider is that while chips are information processing systems, they are physical systems too. Some of that low level grunge may be the result of the chip's own self exitation as it converts an analog audio signal into radio frequency pulses. I believe those fine vibrations contribute to the chip's overall sonics. With the RF-57 tuning buttons in place, both the resolution of low level information and the quality of it was markedly improved. I was hearing little wispy tones and nuances that simply weren't there in the stock amp. I also noticed that as the amp played for a while this quality of "organicity" would improve to the point where I wasn't thinking about amplifiers or hardware....
Follow Ups:
Unless bridged systems are very well balanced, they'll add up their noise. That noise is a product of the algorithms that were built into the design and no vibration control will reduce those.
But the chip and board vibrations may be reduced, obviously.
