Good AC adapter for my headphone amp

[pedxing]

I am looking for a better and cleaner AC adapter for my generic CHA47 amp. Right now, I am using a 12 V radio shack walwart. I want something cleaner so I won't hear so much static after I crank up the volume know. The static problem goes away when I use 2 9v batteries, but I don't like to use batteries, especially after I found out how expensive good rechargeable 9v batteries cost.

I don't think my amp can safely handle a 24v AC adapter without frying itself.

Maybe I should upgrade my amp to something more trendier and more compatible with my Beyer DT-931 instead of getting a better power source.

Any suggestions?

I'm sure Elpac makes a regulated power supply with lower voltage than the 24v supply everyone always raves about.

I have a pair of DT931s too and I've tried them on various amps. I would have to say that the better the amp the better the DT931s sound. If I were you I would worry about getting a better amp first.

Any recommendations what type of cheap DIY amp to replace my old one? I prefer to spend less than $150 for a new amp.

Just wondering. On my cheap radio shack adapter, it has a adapter plug on the tip. I always get confused about its polarity. The negative side (minus sign) is on the "tip" side. Does "tip" refer to outer diameter or inner diameter of my 5.5 tubular plug?

I don't recommend the elpac. With my meta42, it seemed that the music gained a harsh edge and the increased slam gave me fatigue.

I believe it refers to the tip. Most AC adapters are center-positive, meaning the inside is the positive side.

Never heard one but how about a Headsave amp. The Go Vibe looks good and at that price you can't beat it.

You could wait for the next bulk purchase of the $110 Hybrid Tube amps from Japan after hearing impressions
