The best way to answer that is if your M-50s can be heard through a normal PC sound card or MP3 player then YES the HOTUSB1 will be able to drive them quite nicely.

There's a review linked that said these headphones are easy to drive so i think you would be okay if you went with the cheaper hotusb1 over the mark 4.

I just ordered the Hotusb1 and I must say that Dave provides the best customer service I have ever experienced, hands down. he worked with me in figuring out an Ebay issue and then once I ordered one from his online store he had it tested and shipped within an hour and a half. I can't wait till it comes in and I can experience for myself all the great things people have been saying.

I second the above opinion of HotAudio40 Customer Service. I have also just bought a product from Dave, the TPA6120A2 Based Headphone Amplifier with a 32 Step Digital Rotary Encoder Volume / Balance Control. I received a Second Chance Offer on an eBay auction and got the amp for much less than his asking price, a true sign of generosity. Several prompt emails (I'm in Australia, he's in Winnipeg Canada!) later he wrote that he'd gone out in -40C weather to post the package off and forwarded a CanadaPost lodgement number!
I too will be submitting my impressions of this product. This kind of service and active involvement is what the Head-fi experience is all about for me. As an aside, I got the same level of treatment when I bought my PA2V2 from Gary, another good Canuck pro-DIYer who contributes to our hobby.
These guys deserve our support and the more of us who buy from people like Dave and Gary, the better the products will become. We can be active in this process. More of life should be like this.

So what sounds better exactly? The HOTUSB1 or the MarkIV? My IEM's don't need much power to run them, so power issues go out the door. I am speaking on a purely sound based standpoint.
Also guys for who have used these, how would you rate them to say stock sound card?
Thanks!

those are the IEM's i use. Specs say 119dB per mW.
Oh and forgot, i would like these also able to drive Beyer 880's reasonably well.

Well the MARK IV is probably way too powerful for those IEMs.
119dB is very efficient so the HOTUSB1 would handle them nicely.
As far as how much power the Beyer 880s require, I really can't say as I've never tried them.

I can add an attenuator to push them up to 250 ohms from 29 ohms or so, so that should reduce their efficiency dramatically.
But on a purely sound based objective, which of those two do you think sound better?

Adding a resistor would totally destroy the sound quality, but you could also turn down the volume
My best USB DACS are the HOTAUDIO SUPREME, MARK IV, and HOTUSB1 in that order.
PM me if you want to know more.

This very, very hungover Christmas morning I was surprised with a HotUSB1 from, of all people, my mother. Probably the result of a collaboration between her and my girl, but that's besides the point.
It's been burning in for a few hours now so I figured I'd give it a quick listen, just a song or two from Ephrat's No Ones Words. I only have my HA-RX700s with me, so it's Foobar > HotUSB1 > RX700s.
Immediately I was impressed with the soundstage. Much larger than my laptops onboard sound. Bass sounds good and tight, treble is crisp, everything is as it should be. No interference or clicks and pops (unlike the onboard sound). I'll see how it progresses and does with my 2200s later.
In my inexpert opinion, for the price (well, for me it was free, but you know what I mean) I've got to say it's a nice upgrade. I'm kinda upset at myself for not having bought this a few months ago when I first ran across this thread.
Now back to the family, and Merry Christmas!

I own a HOTUSB1 (with PCM2707) for a while and really like it
But even with a PA2V2 amp not powerful enough to drive my 400ohm AKG K340 (with high gain it was loud enough but there was a distortion).
A QED MB45 was enough with 2 Watts R.M.S. per channel.
Any chance the MARK IV will drive it?
