I can't seem to find it, had problems with my Windows user profile and had to blow it away.   http://www.xduoo.com/xduoo/En/DownList.Asp   Assuming it is xmos-usb-drive-xxx either of those files

I can make the drivers available, have them on my Google Drive, not sure if it will let me post links to files though, let me know.

The TA-01 is extraordinarily harsh. Tons of power, but ....   I'll be replacing the tube with a Gold Lion and will update with the results.

Looks nice, thanks.

I picked up a Topping NX2 for $55 CAD (@ $45 USD), no power, even for powering some lower impedance IEMs. I'll probably pick up something better in the winter.

Thanks for the advice on the Focal's, and on how you feel about various sound signatures. A family friend swears by the Focal studio monitor speakers. I didn't consider the difference with open back headphones and sound leakage, and this will be a concern in the office environment.   So much...

Thanks, appreciate the feedback. Most of the listening I do will be at the desk, and if mobile, it will be IEMs. I bought a portable headphone amp and it doesn't offer much more headroom before clipping, compared to the stock amp in my Huawei Nexus 6P, will probably splurge and get a better...

Thanks ProtegeManiac ! That's great information, especially on the frequency response. I'll have to demo the Sennheiser HD650, and possibly stick with the Etymotic HF5 IEMs until after the trip.

Thanks very much for your time.   I'm in the process of evaluating full headphones, which will mainly be used at an office job without totally breaking the bank. These would be powered by a USB headphone amplifier with tube preamp and class A amp, probably a watt or two output, in an office...

This thread is long dead, but I purchased the 2015 version a few months ago and am thoroughly impressed. I'm not an audiophile, but I grew up working for my father who ran a pro sound shop and dabbled in some retail. My general preference is for a neutral sounding speaker or headphone that does...
