Earlier this year I mentioned on here that I purchased an AP10H but found it was too loud, meaning that I couldn't turn up the volume beyond 9 o'clock with my Sennheiser HD650 headphones. Any more than that and it was getting into hearing damage territory. I also commented that I found it was lacking in bass.
Richard replied and suggested I sent it back for a simple fix to adjust the sensitivity which would sort both the volume and bass issues. I never got around to it. As he's sadly no longer with us I thought I might try some inline attenuators. Rothwell make them and they're on ebay for £38.99. They come in 10, 15 or 20 dB attenuation levels. Would this work and if so what attenuation level do people think I should get? I'm tempted to go for the middle range 15dB model.

Re: AP10H and inline attenuators
You'd get the levels reduced on the volume control certainly so you could use more of it's range.

Re: AP10H and inline attenuators
My experience is that you would also get a reduction in sound quality too. If I remember correctly they are just a resistor inside an in/out Phono plug. You might be better with something like the P20 between source and AP10H from sound quality perspective.

Re: AP10H and inline attenuators
Once we get the new company up and running, Tomasz will give you a quote to adjust the sensitivity.
The Rothwells do degrade the sound - I have a pair here that I was using to 'tame' a very sensitive line input on a Sugden amp. You're welcome to try them...

Re: AP10H and inline attenuators
I'll wait for the new company to get going and get it modified, there's no rush. Thanks for the info.

Re: AP10H and inline attenuators
Same goes for the Russ Andrews attenuated cables for CD. Much better off without them though this isn't so much an issue with modern amps. I will shut up now because I want to sell one .savvypaul wrote: ↑Thu Aug 08, 2019 10:18 am Once we get the new company up and running, Tomasz will give you a quote to adjust the sensitivity.

Wallace, it's always good to hear from you, relevancy is overrated.
