I have a minor, mainly conceptually problem I wouldn't mind help on. I am using my AVR (Yamaha RX-A2A, same as the RV-V6A measured here) front preouts to integrate with my 2 channel system. However, my measurements are even worse than Amir's for DAC performance at high output levels. I have traced this to the inability of the DAC to drive anything with an input impedance below 47kOhms well. My preamp (Lyngdorf DPA-1) and measurement device (RME ADI-2 Pro) both have 9-10kohm impedance.
Are there good, cheap products that may help increase the impedance the AVR sees? I can't seem to find a cheap, well performing buffer amp at all that is not DIY. Perhaps something in the pro field? My pre-amp immediately digitises analog inputs so even an ADC is an option. The pre-amp also has a balanced input so even a well performing unbalanced to balanced active converter (with high input impedance) would be an option as well.
Can anyone identify a suitable product?
