Product Description

We significantly upgraded the award winning dac25.2 to the dac25.3. The upgrade was to the USB input which now accepts 24bit/96kHz signals. The dac25.3 is natively compatible with Windows 7/Vista/XP/2000 and Mac OS X. Today an increasing number of music lovers are buying storing and listening to music through their computer, media server, or personal music player (iPod). Many are also digitally distributing their music using a sonos, squeezebox, or one of a host of digital music distribution systems available on the market. This is a great way to explore and appreciate music but generally it's done at the expense of sound quality. Until now music lovers have been forced to rely on the inferior digital to analog converters (DACs) and sounds cards contained in those devices. As a result, their musical enjoyment has dramatically suffered. We designed the dac25.3 to directly address this problem and to significantly improve the sound quality of the music played on these systems.

This makes placement a little challenging.

My wife walked into the room a minute later and said she could immediately hear the difference the Music Hall makes.

There is a lot of controversy about what a DAC needs to be and how much it should cost. Some would say you are insane for spending 600 bucks on a DAC and some would say you need to spend an order of magnitude more. In my research I found that I might get a DAC that sounds as good as the MH for less money, but this unit has functionality the others don't. My review:

Sound- It sounds great. A good DAC should faithfully reproduce music and eliminate jitter and other artifacts you hear from digital sources. It's a simple task. This does just that, but with an added bonus. The tube output stage tends to warm up the sound just a little bit, and gives a little more life to compressed audio files. This is subject to taste however. Some people prefer a more clinical sound. Me: I prefer the warmth.

Features:
- It has a built in headphone amp. Nice feature. It sounds good, but I'm no expert on headphone amps.
- It will up-convert your stream to 192kbps or down-convert to 96kbps. I tend to leave it in auto mode. I don't think it adds anything to up-convert.
- The unit will switch itself into standby mode when it loses a signal.

Inputs: It has a lot more inputs that similarly priced DACs. USB, optical, coaxial, and XLR. I use the optical and USB inputs, and the unit intelligently switches between the two when one signal is lost and another is present. This is a nice feature, and necessary because there is NO REMOTE.

Build: It is built very well. A quality piece of gear. Buttons and dials operate smoothly with just the right amount of resistance. I have a complaint about the form, however. It is a little long and skinny. Not longer than many 19" deep components, but longer than the other music hall gear it is designed to go with.

When I first installed the DAC, I had an incredible hum coming through the speakers. I had never had that before. I suspected a groundloop hum but had a hard time tracking it down. I emailed the company info email and got an almost instant response from Roy Hall, the head of the company advising on steps to take. Through several exchanges, I identified and solved the problem which had nothing to do with the DAC. It was great service and response. I bring this up as it may be the only time when I have corresponded with the head of a consumer products company on what I though was a product service issue.

I have connected the DAC to my PC by TOSlink and then to a Rotel pre-amp and amp with Totem Forest speakers. The extended range and clarity of the music I had listened to so many times before more than convinced me I had made the right choice of a DAC. I tend to listen to jazz and classical which have an extended dynamic range and I heard a number of details I never heard from those pieces before. There are an incredible amount of choices out there but you should consider not only the reviews of the product but what the company does when you think you have a problem with their product.

I am very happy with my choice of this DAC after alot of research.

This is such a great DAC that I now have two. Both are running through vintage accuphase amps into Vienna acoustics Haydn speakers. I use iPods as music servers through Wadia transports. To get the most out this DAC, make sure your files are lossless or WAV. Anything compressed wont give optimal performance. Second, ditch the supplied electro harmonic 6922 tube. Get a vintage 7308. Driver grade is fine. You can get a NOS 1960s Amperex 7308 for around $50. The reason why you want a 7308 is because it has a10,000 hour getter life. With a decent tube, this DAC has a great warm and personal sound. Too many DACs are overly analytic and sterile. This one sounds wonderful, especially when you can get a nice tube sound using solid state components downstream of the DAC.
