Input to Topping Pre90

[sganti]

Hi
I have a benchmark dac3B, and got a topping preamp, the balanced output of the benchmark with no attenuation is +24 dBu @ 0dbFS, Topping spec indicates an input sensitivity of 9.3Vrms @ 0dB.

Given this is a preamp with an attenuator, is it ok to leave the benchmark at the factory setting of maximum gain, since the attenuator will help in not overloading the preamp? I am assuming the attenuation is done at the input..

The preamp drives a pair of tube amp monolocks I built, the amp configuration is choke loaded 801A driving a 211 using monolith magnetics plate chokes, output transformers and power transformers. Given the low drive, I need as much gain as possible going into the amp to drive the 211 to full power.

Thank you

I did not get a response, maybe my question was not clear :-(

let me re-phrase, does topping pre90 have the relay attenuation at the input or output, I am assuming at the input, in which case I should be with benchmark dac3B putting out full output..

can the experts here confirm please

thank you
