Pre and power matching

[Speedskater]

Measuring any solid-state line-output into a 600 Ohm load (if the output was not designed for 600 Ohm loads) is just wheel-spinning.
Now a 2000 Ohm load test is reasonable. (if the design load is 5 to 10k)

It is my point - you can´t compare the Vout's -VTL specifiec 1% THD at 10 kohm load , ARC .5% on 200kohm.

For the REF10 the most important specification is the rated output : 2V RMS (1V RMS SE) into 200K ohm balanced load - it will produce a power of 200W in a 8 ohm load with a 26db gain power amplifier.

And as far as I could understand the offset gain of the REF10 only affects the attenuator/display settings, not the gain block of the preamplifier. It is just an display added convenience. But I can be wrong, please check it!

Francisco,

Unless I'm suffering from Amir-induced audiophile delusions I could hear a difference between the different gain settings on the REF 10, with digital, and with the phono preamp well. That's why I found it such a nice and useful touch, and thought worth mentioning here...


cheers,
alex

It's not audiophile delusions, there are real engineering reasons why it could happen.
