Another new DAC: Audio Mirror

I think the prevailing attitude is not so much driving a woofer with tubes but the amps ability to control it based on damping factor. I'm no expert and it sounds like you had a positive experience. What are your speakers rated for efficiency?

95 dB.
But my point was that a DAC or a preamp does not drive speakers, and I don't think you should have concerns about the low frequency performance just because the DAC has a tube inside... especially with this DAC. 

@vassils Can you say what you’re using to run your woofers? I have Coincident PRE’s (94db) and just finally got dedicated subwoofer amplifiers to run their lower ends (2 x 12"). They’re the solid state Class AB Dayton Audio SA1000s that Audio Kinesis uses for their Swarm, supposedly based of a Bob Carver design. So much cheaper than everything else in my system, but made an amazing difference.

And thanks for the comparison to the Terminator, that’s good to hear, as it was another I had considered before buying the AMT3se.

@cal3713 - I am sending you a PM, so we can keep this thread on topic. 

@vassils.  Thanks for the information!
