Ok, late to the party here. Put my order in Sept. Just got my new modded Mac Mini back from Alex Crespi at Uptone Audio. He gave me "the works". He spec'd out the 1.1TB SSD and install the MMK fanless kit and well as retro'd the MM for his JS-2 Linear PS.
Hooked up the Regen last nite with the SMPS supply that comes with it. Listened to it with it in and out and out and thought "eh" it's an OK improvement. Maybe 3-5%. It's perceptible but not an OMG moment.
This afternoon I unpack the LPS and run it to the Regen. Now we are talking serious sound improvement. Sounds like a major component upgrade. Wow! Now I'm a believer. Music is revealing itself like it never has before. Listening to the double bass player in an orchestral piece, he no longer sounds like he is playing behind a thick velvet curtain but prominent stage right. Listening to James Morrison's The Nearness of You intro with layers of harmony, I can distinctly hear each voice clearly, close my eyes and I can see them too!
I'm now an apologist for the Regen and what it can do!
I haven't even hooked up the new MM yet either. Figure that transfer will take all night using Migration Assisstant without a Thunderbolt connection. Besides I can't tear myself away now!
I can only imagine what tomorrow's sound will be like with the new modded MM in the mix!
Thanks to all that pointed out this improvement. Well worth the while and the wait.
