Anyone?
I apologize for the noob like question.
I apologize for the noob like question.
Can it output optical sound and audio to my headphones at the same time?
Do you guys think that the Audinst HUD-MX1 would pair nicely with the Sennheiser HD 598. I'm kind of looking for a DAC/Amp solution under $200. I was also looking into the E9 + E10 combo, again, under $200.
Could anyone possibly recommend me a good linear regulated power supply (kit or full product) for this amp? I need a good 15V power supply for my Audinst HUD-MX1.
I'm looking at something like this right now:

It looks fairly high quality but remains economical.
Another question: How much current does the Audinst need feeding it from the power supply when it is driving a set of 600Ohm headphones? I need to choose an appripriate transformer, as I want it to be as compact as possible while providing enough power to run the thing.
EDIT: Screw it I'm taking the DIY route and making a 1A linear regulated power supply of my own. You can check out my schematics and stuff here: http://wp.me/s1OOFO-yzlrps

The issue with the stock power supply is not really the output current though, it’s that it is a fairly low quality switching power supply. A good DIY linear regulated power supply should have much lower output ripple and better transient response as well.
Mike from Headphonia also tells me that battery power is an improvement as well and also mentions that the internal regulation of the Audinst is rather lacking. Indeed I didn't see anything too impressive when looking around inside the Audinst, [http://i429.photobucket.com/albums/qq20/Yangorang/Audinst%20HUD-MX1/CIMG0568.jpg] but I am somewhat hesitant to start desoldering stuff on the inside without really knowing the topology.
I'm surprised about his comment on the audinst lacking regulation... the product page makes it look like it has a solid set of regulators. I suppose a reviewer is more reliable than the commercial page though. If this is really the case, then it would make even more sense to get a linear regulator for the Audinst.
