Of course you can ask. ... :-) ... I connected them to a friend's pair of Avantgard Trios...

...and discovered just how much the amps amplified and the speakers made more audible the noise of the linestage's tuberush.

I think this particular system could do with at least 10 to as much as 20dB less gain than its rated 27dB. Previously I had my 12dB-gain Music Reference EM7 amps connected and the system was virtually dead quiet, noise being audible only with one's ear virtually inside the horn.

If as Triode_Kingdom wrote, a fixed Voltage-divider network is appropriate, could it be installed after the 2nd 6SN7 gain stage, say after the 2nd coupling cap, thereby quieting the fontend's inherent noise?

I have copies of the schematic I'll send to anyone who e-mails me at jeffreybehr(at)cox(dot)net.
