AR SP8 mk2 high output volume

Hello everyone, thank you for accepting me in this group. I have my AR  SP 8 mk2 preamplifier and I would like to know your opinion and if you consider its high output volume a problem with this power amp. Problem is the volume control is too low,  Very sensitive amp. I can't use much volume control.Does this affect the signal quality or is it just a drawback?I just want to know if it's something I need to worry about.

here I put the specifications of the power amp Puresound A30
ower output (Class A operation) 30 Watts/ch Ultra Linear, 18 Watts/ch Triode Coupled
Frequency Response 20Hz - 20kHz -0.25 to -0.3 dB
THD 0,3%
Input Impedance 100 KOhm
S/N ratio 88 dB
Input sensitivity for 0dB 100 mV
Power Consumption 260 Watts
Net Weight 28 Kg
Dimensions (mm) 436 W x 360 D x 190 H
Inputs 3. Line Level
Outputs 4 & 8 Ohm
tenoris

Good to know the A30 volume pot does not degrade the signal when set lower than full. I learned something.

OP, 

If the Puresound A30 is to be used as an amplifier (i.e. driven by a separate preamp), its volume control should be fully turned up. You are definitely degrading the signal if it's at 1 o'clock.

As mentioned, given the mismatch between the AR and the A30, it would be best for you to use the A30 as it is, an integrated amp.

Tube rolling is one thing you may look into if you're looking for a particular sound. Start with the driver tubes if you wish.
