Jeff Rowland aeris Jeff Roland Aeris DAC

The gorgeous Jeff Roland Aeris Dac.  This one with original box and manual.  J Roland's Aeris has received accolades from every major review magazine.  There's a reason.  ...It's one of the most natural dacs we've ever had in house.  Certainly if you own a Roland amp, this is a no brainer...or if you have a solid state amp that could use some depth and nuance, the Aeris would fit the bill.
Just put in Jeff Roland Aeris into google to read any of the many reviews.  they're all stellar. This was a trade in from one of our clients on a Rockna Signature Balanced DAC at double the cost

Conclusion

By now I am running out of ways to express how I feel about the Aeris DAC. It is not only the best DAC I have heard to date but also the most consistently well-performing one. No matter the placement, cables or source, the outcome is always superb. Also important to note is that while the Aeris does have the typical super-refined Rowland sound, it can also boogie with the best. This is a super-natural, highly civilised but supremely dynamic performer that I expect will work well in various setups. My feeling about the Aeris is best described as follows: “I must have it”.
