Volume issue

Hi, I recently hook up my 2 channels system again and found out something I didn't notice before. The problem is whatever sources I input to the pre amp and power amp which are Audio Research SP10 and D125, I can only turn the volume about 9-10 o'clock position. The sound is too lound from my B&W 805. Anything wrong? Any idea?

Thanks.

Sorry, haven't got a clue. I doubt that they are retailed by B&M stores.

If there is a degredation in the signal from the insertion of a Rothwell 10db attenuator I really don't hear it. It is after all just a single resistor (encased in a rlug with male and female RCA's) put in the line. You place it at the amp and there is minimal, if any change, in the impedence values either. You can buy them on the internet for about $60 a pair. Use Google to ID a merchant. If you can't find one let me know.

The efficiency of your speakers may be too high for more flexibility with the output gain of the SP10. You can do two things. 1) Engage the switch on the front panel which lowers the gain of incoming signals 6db. 2)Or put in a fix attenuator, like those made by Rothwell which have 10db reduction. The benefit of this is that you will be lowing the noise floor of your SP10 - say good by to the hiss which is noticible with high efficiency speakers. I used both methods with speakers with a 92db efficiency. I got by OK with 86db speakers (+a bit of noise) by using the switch on the SP10.

Hope that helps.
