Hi,
I am considering having a 4-channel Sigma/Beta 22 built to use with my HD800s. There are a number of upgrades available. I wanted ask this more technically oriented forum if they feel any of these are worthwhile:
1. Additional Sigma 22 power supply (comes w/ additional 80VA toroidal transformer)
2. Goldpoint stepped attenuator upgrade (quad channel)
3. Power supply upgrade: 100VA transformer, 6800uF x 2 filtering capacitors, ultrafast HEXFRED diodes
A) none of these
b) better attenuator over stock Alps potentiometer
c) add a second PSU
d) upgrade the transformer(s)
Which of these or combinations of these is worthwhile and why?
Thanks,
Bob
