TRL Audio Mirror D1 Signature


I recently had my Audio Mirror DAC modified by TRL. A review has been posted in the Product Review section. I will say that anyone owning or thinking or purchasing this DAC should consider this modification which is quite reasonably priced at $550. The DAC sounds quieter (-20db reduction in noise level), is more accurate and analog sounding (it was already a very analog sounding DAC so this improvement truly surprised me), and really improves the micro and macro dynamics. The overall presence of the music is much more pronounced. Notes just seem to appear or jump out at you. Truly an amazing upgrade, but be forewarned, it will require a 500 hour minimum burn-in process.

Let me know what you think of it. Also, if you like it and after a while of use want to get more mileage out of it, give TRL a call. They'll take it to well beyond the next level.
Can anybody describe the signature or what to expect from the TRL mods? Is there a common quality of sound that is associated with the TRL mods? Did anyone have more than one piece of equipment modified by them? Just curious what can be improved because their mod is $550 regardless of the unit being modified. Just curious.....thanks
I have one of their solid state amps, the modified D1, and soon I will have the modified Sony DVP-NS900V. I have recently heard the modified Sony in another set-up with VMPS speakers and Atma-sphere monoblocks.

One of the things I notice about the TRL house sound is the lowered noise floor resulting in increased micro and macro dynamics. I really feel this is where TRL excels. Their ability to squeeze every last ounce of detail that a unit can deliver is amazing. Listening at low volume levels has never been easier. My neighbors love it.

As for the tonal qualities, with the digital mods the bass is cleaner and tighter. The highs lose the graininess (digititis), and the mids flourish, but aren't overly sweet.

The amp differs somewhat from the digital mods in that it is very transparent. It provides ample power and is extremly quiet. Musical reproduction is very accurate and it will expose any weaknesses that may exist in your system. I am using a tube preamp right now, but will be trying a passive preamp shortly that should give me a better idea of the TRL house sound.

I hope this helps. If you're in the SoCal area you're welcome to stop by for a listen.
Clio, thanks for your comments. I appreciate the offer to come by and listen. I am in NYC so it won't be possible. I just wanted to get a feel on what to expect from TRL mods. I did talk to them and they explained what the results of the mods should be, but I like to hear from someone who had it done. I understand they do some re-wiring of power supply, dampen the board and clock, etc. But it is tough to think that it goes beyond that for $550 as far as replacement of caps, resistors, etc. Just reducing the overall noise floor of the unit can go a long way. Which is a good thing if it can be properly achieved without sacrificing other things that the stock unit did well.
