The BUDA will sound the same with balanced or single ended inputs (through the phase splitter).  The nice thing about your Ultra Micro DAC is that it is essentially a Max DAC. Not only will the modules be better in the BUDA than the older Balanced Desktop, but your Ultra Micro DAC is a better...

The iPad one and iPad two will most likely display this message "The attached accessory uses too much power." You will need to pause the music, and turn the Bithead on before you plug it into the USB connection. Then it will not be asking the iPad for power. Once you have plugged it in you can...

Hey MangoMonkey,   I think the Micro Stack should work just fine for the 225s.  You may find that the HR amps are a little warmer than most other solid state stuff anyway, and turning on the Crossfeed can sometimes help this as well.  I would use the medium or low gain setting for the 225s...

Hello tnili,   The UDAC can support those incoming signals (88.2 and 176.4) on coax or optical, and will process them like any other incoming signal. The light on the front panel should display the nearest sample rate value. the UDAC can only accept up to 16bit/48kHz on USB, but any incoming...

Any of our DAC products do indeed output a line level signal and will be perfectly compatible with any receiver/aux or preamp input.

Recently, the graphs were reformatted, and there may have been a couple that were overlooked since the products were discontinued.  I will look into getting the 601 graph back up on the site.  Thanks for the heads-up.

The intended use of the preamp output on any of our amps is to drive a power amplifier. Whether the power amp is built into powered speakers or a separate amp driving passive speakers. The headphone amp itself is functioning as the preamplifier. In essence, the preamp out is very similar to the...

Hey there Head-fi'ers, Well, the time has come that we are seeing the last of the Ultra Micro DACs.  We have decided to clear out our inventory and offering a killer sale on the last of our units, now only $449.  So, come get 'em while they last!   Please Call the helpful HeadRoom Sales...

The 600ohm DT880  is relatively new here at HeadRoom, and is part of a group of headphones waiting to be measured. We will try to get those done as soon as possible and get those measurements posted.  Thanks for the heads-up :)

I would contact Mike O. in our repair dept.  He should be able to troubleshoot specific issues with you. 

Thanks for the positive feedback.  We always try to provide the best customer service we can
