Trouble installing Fetishizator into Rotel rcd-971 (pcm63)

[Chilli6565]

Hi,
I have just installed the Fetishizator into my Rotel rcd-971 and although it is working and sounds great, the gain is too low.The dac chips are the Burr Brown pcm 63..pins 5 and 6 are shorted. I believe the Fetishizator was optimized for the tda1541 dac?..I hope the picture of the circuit comes through so to make it easier to comment.😎

Thanks
chill

pretty please

...anybody?...gurus welcome 🙂

That circuit does not have enough gain for those Iout DAC's you mentioned. Nothing you can do about it, apart from increasing the Iout resistor value and/or increasing the fetishizator gain, but both solutions will give high distortion / cripple frequency response. If you are happy with sound, consider using “interstage” gain - like the pre-amp, between CD player and amplifier.

Just curious, Chilli - how did this work out? I have a Rotel RCD-971 as well, and I'd like to tube it; so any tips you can give would be appreciated.
