Sorry for your confusing, I meant the R20 problem.

They are exceptionally well controlled with this amp. I look forward to trying the opa627 or opa637 but in the other fi.Q. The combination of the MB-1 optical in dual dac, iRiver H140 and lossless with the fi.Q is a powerful combination. |

Ryuzoh said by removing R20 and just jumping it would sort out the hiss. I've had a look and think I'll leave it as long as Ryuzoh can just confirm that there is no underlying issue regarding this. I have decided to use the Fi-Q as my home amp replacing the PSU1 Solo, this will be going on e-bay in the new year once I get the Fi-Q back from Maxxing out...... This certainly is some amp. |

For these I can use high current draw heater tubes like the 55 or 27 or the lower draw, 76 all with a flick of a switch. I can also change the voltages on the tubes, according to the tube used. There is a nice combination of quality components. My external power supply is a dual regulated mono power supply source that used two 6X4 tubes per supply for the initial rectification with a final output of 480 volts that is pretty much ripple free but I still use 4 inductors in the preamp. There is more but maybe I am a tube guy more than solid state. The fi.Q options are fun though and offer challenges and rewards. |
