I couldn't try your suggestion until this morning when I collected my Rega P7 TT + Cartridge after being serviced by my local hifi adviser here in Winchester. My amplification consists of an AudioLab 8000Q driving an AudioLab 8000P. The 8000Q has two identical RCA line output socket pairs , so I was able to connect the Behringer UAC-202 to the 8000Q line output which was not being used, allowing me to continue to hear the music while digitising it via the Behringer.
The results have baffled me: the 'histogram' in Audacity was now an almost perfectly straight line. It could be adjusted using the volume control on the 8000Q (obviously) but only became a recognisable recording 'plot' when the volume from the speakers was at an uncomfortable level. Playing back this recording either through the Behringer to a tape input on the 8000Q or via the in-built speakers on the laptop or via the speaker output connector on the laptop into Tape-In on the 8000Q produced a barely audible output on my main speakers (Spendor SP1s). I swapped the connections on the 2 line-outs on the 8000Q - no difference on the volume on the main speakers and no difference to the recording levels on the laptop either - still just a straight line, much much quieter than connecting the Behringer UAC-202 to the output of the 640P. I tried by-passing the Behringer entirely, using the mic-in connector on the laptop connected to the output of the 640P. The recording volume was now higher - but no higher than when using the Behringer taking the signal into the laptop via USB (but of obviously poorer quality using the ADC backing the mic-in on the laptop),
Bottom line: I think I need your re-engineered quasi-640P running with about 64 dB gain!. But I'll talk to you outside this forum to agree the details - is that OK?
That's absolutely fine Tony. Nice speakers BTW!
