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.
Deb,

If you go to my review you will see more details. Right now the only comparison being made is to the stock unit.

Prior to deciding on the stock Audio Mirror I auditioned a number of DACs, most in my system, but others in-store. They included: Audio Note (1.1x and 2.1x), 47 Labs Shigaraki, Benchmark, MSB, and Bel Canto. I am going to place an order for the Audio Sector DAC shortly and will makes some comparisons to that unit.
Jman66,

I can tell you that the FET output, hexfreds, and Auricaps aren't going to make a significant difference between the stock units. However, the TRL modded unit will outperform the D1 and although I haven't heard it, I'm confident will also outperform the D2, both by a wide margin. I asked TRL if using the newly upgraded parts would add value to their mods and they were pretty ambivalent about it. In fact they were pretty impressed with the stock caps in the D1 and were confused why Vlad would go with Auricaps. They didn't see the need to upgrade that area of the DAC.
Joeylawn36111,

The modified unit requires the extended burn-in. The D2 should be good to go after 200 or so hours.
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.
Audphile1- TRL made a huge point to me that the D1 in stock form was excellent and one of the best stock DACs that has come through their shop. It has a simple circuit which makes it easy for them to work on. TRL usually likes to replace the output caps, but in this case the stock ones tested well so they didn't bother. As a mod shop they stay away from the $40 bag of parts approach and focus on many of the things you mentioned that result in a lower noise floor (20db on the scope in my case) without sacrificing the integrity of the stock sonic signature.
Dbld - money back guarantee if you don't like the mod. Not much risk except shipping cost. No one has taken TRL up on this offer after receiving their modified player. This should give you added confidence in TRL's capabilities. If you really like your player and want to squeeze a lot more out of it this is the most economical route to go.
