For those interested, there is a website which does an in depth look into the technical
aspects of this amp. Its an interesting read, especially if you're considering purchasing one.http://www.michael.mardis.com/sonic
This is probably a dumb question, but can these be used as a generic headphone amp? From what I've seen, they're cheaper than most dedicated headphone amps. I'm getting distorted bass and overall bad sound from my computer's headphone jack so I'm thinking an amp may help.
Yes you can, but with one word of caution though: With higher impedances this amp ramps up the high end frequency response, don't know exact estimates but its after or around 20khz. Ti's equibit amplifiers do this and some others if not all analog switching amps do too I believe- the tripath design is not the only one. Of course cd players don't play ultrsonic frequencies, but there still may be a noise in the ultrasonic range among other interferences from other devices. From reading a post on DIYaudio it seems that the lowpass filter on the amp is at about 60 or 70khz. If you have really high impedance headphones, say 300 ohm, the poster over at DIY figured it would be around a 6 db increase around the 40-60khz range. If you're listening at high volume levels another 6db could be damaging to your hearing if
ultrasonic frequencies damage hearing. The only way to combat this is to lower the low pass filter frequency. If I had one of these, I could probably find it, but I don't, sorry
If you have headphones with low impedance, 16-32 ohms you may be ok. Also if you listen to mainly cd source, you may be ok. I really don't know the effects of ultrasonic frequencies on hearing, maybe someone else will chime with the answer. I just noticed the caution the poster over at DIYaudio gave and thought I'd spread the info.
Here's a pic from another topic about the xr10 and its frequency response versus impedance. I'm guessing tripath would be similar.
Edit: Looks like machani found some supporting evidence, looks like a no-go for a stock T-amp and headphones.
