For the price, I don't think you can get anything better. Sure, Benchmark Dac 2 sounds better but it's 8 times the price. I think it sounds great with hi-fi systems and headphones such as Sennheiser Momentum, AKG Q 701 etc... If you have a 20.000 dollars high-end system then it may not be enough?.. I wouldn't know as I don't have such an expensive setup. Then again, TEAC is a well known, quality brand and because they can mass produce, their prices are always lower than small companies such as Schiit, Arcam etc. For instance everyone thinks Arcam's dacs are great but I prefer the UDH01 to them. They have that weird Arcam house sound that I don't like. Benchmark Dac 2 is very neutral but it's really expensive. And it's not better than Teac's UD-501, DSD capable DAC of Teac. Sometimes people pay lots of money for brand name. Meridian Prime for instance. Is it good? Yes. Is it worth that money? Hell no, it's not.
In short, the rest of your hi-fi setup matters too. But I find Teac to be an admirable performer and see no reason to buy anything else. It's great for general listening purposes. I also use it to watch films and everything sounds great.
By the way, sometimes I used to get a weird static noise when I wanted to start another song or wanted to stop and resume the song. I changed my laptop's hard drive to SSD (solid state drive) and installed Windows 7 64 bit from scratch and I don't get any static noise anymore. The dac works beautifully.
