cd player + preamp = too much gain


My cd player is 2vrms output, preamp is 30dB gain and I can barely listen at low volumes without it being too loud.

I have tried in-line attenuators to no avail (the sound deteriorated noticeably) and also replaced the 12AX7 and 12AX7 pairs with lower gain tubes...still no major improvements.

Are there any options left?

Hi Al,

I used "Goldenjacks", which as supposedly more transparent than any other in-line attenuator. I tested them on the input of the preamp and also on the input of the power amp - the 10dB pair almost had no effect on the sound, but the 16dB basically destroyed the sound altogether. Other people have reported great things about the Goldenjacks, but this seems to be with solid state amps.

I wouldn't mind trying the Rothwells, but getting another set would be yet another hit to the wallet when i think what is ultimately needed is a cd player with an output that is not so hot, or a preamp without 30dB of gain.

Could it have something to do with the quality of resistors in the inline attenuators?
Thanks Al - not sure if I'll fork out more $$ to do that test! Might just get a passive volume control and leave it set at a certain level, at least this may save the experimentation with different in-line attenuators.

Any idea as to what manufacturers have a good reputation for not altering sound too much?
nifty machine, functions as a switch box too - have configured yours for non-variable outpout?
hi Bob - yeah I really didn't like them. Still searching for another way...might just ditch the preamp and get the Lightspeed Passive ... seems a good option....
Just found these which could do the trick - any ideas as to the quality of parts;
