A meeting of the minds occurred and all were better for it.
As I had hoped, the modified MAC Mini as prepared by my friends Darrell McCombs and Kevin Burke was a resounding success. Just how much of one will take some 'splaining so here goes:
Setting up and getting ready for an audio show is one of life's minor pleasures, kind of like mowing the yard. You know that everything will be better when it is finished, but it is just drudge work. Along with this is the "don't change anything, it sounds just fine" thing that accompanies being tired, frustrated and hungry. When we first set up, there were the typical little bugs that had to be swatted and worked through, but we were pretty much happy with the sound of DANNY'S 2010 mini running through the new dB Audio Labs Signature Edition DAC. The Signature takes everything that the original Tranquility does and does incredibly well and expands on these qualities. It is an amazing piece. I have had a Tranquility with some prototype mods done to it that are incorporated into the Signature for some time. The production version far surpasses the performance of my modified DAC. It simply kicks butt. What more is there to say?
Quite a 'bit', actually.
Kevin and Darrell brought in their modified 2010 Mini and set it up for comparison. We were all waiting for the sound. I knew what would happen and I think the rest of them were wondering if I was a little off my rocker... until the music started playing. The track was "Way Down Deep" by Jennifer Warnes. About 4 seconds into the percussion and other effects that open the track, Danny got this surprised look on his face. When Jennifer sang her first two nots, Danny got this "deer in the headlights" look on his face

bowed his head and just sat there shaking it. One of "those" moments, you know. He then looked up and said: "We can't go back. This is SOOOO much better." I'll leave it to others to describe what they heard. I have already weighed in on the sound of the Tranquility DAC/ MACH2 Mini combination. It is truly astounding.
There is a synergy that exists between the MACH2 mods and the Tranquility that makes that particular pairing special. Both the base DAC and the SE sound particularly good through the modded Mini. I think that it must be the way that the Tranguiity(s) handle the USB input that makes this so. I heard the MACH2 Mini with another manufacturer's DAC and while there was an improvement, I didn't feel that it was as profound an improvement as with the Tranquility. Again, one of those 'defining moments!'
The dB Audio Labs and MACH2 guys have arrived at an amazing crossroads in digital audio. Their products go together like peanut butter and jelly. Thank you, guys!!!
