If turns out that both the LSA Voyager GAN 350 and the
Peachtree GaN400 amplifiers use the same modules from/designed by
Elegant Audio Solutions. While both have what seems to be different power supplies, the main amplifier board looks identical. The board uses the
GaN Systems HEMT and Elegant Audio Systems is listed as one of their partners. If you go to the GaN Systems website, they have reference boards and detailed information about their reference designs. If you look at the pictures in the reference designs, you will see that those also are from Elegant Audio Solutions.
I had a chance to listen to the Peachtree GaN400 version of this and it at least worked as you would expect out of the box. I (subjectively) had the opportunity to compare the NAD 2200 (upgraded components), GaN400, McIntosh MA252 and the Purifi Eval1. Being an engineer myself and a believer in numbers I have to say that I have bought several components including the NAD 2200 after seeing the great measurements on ASR and was firmly in the camp of that it would be impossible for me to hear a difference in real life with any of these components. I have to say that I was wrong. In my listening tests I found that consistently of the 4, I picked the NAD 2200 as the worst sounding and the Purifi Eval1 as the best sounding with the GaN400/MA252 somewhere in between consistently. My general observations are:
1. The Purifi amp has a level of clarity, detail and high frequency response that I have never heard on any other amplifier including the Benchmark ABH2. The LSA wasn't bad, but didn't really compare to the Purifi. At about 1/3rd the price, you could buy 3 of the Eval1's for the price of the LSA.
2. You need speakers that can resolve the detail. I found that you need speakers that can resolve the details such as Magnepan LRS, Magico S5 vs. a couple of other speakers that I tried that I just couldn't hear any differences.
Last week a couple of friends and I did some blind testing using the Purifi, MA252 and the ABH2 connected to Topping D90SE and Magico S5MKII. One of these days I will post the results of what we did and how, but if you were going to buy something and you aren't able to try out a bunch of amplifiers, buy the Purifi, it is unlike any other amplifier that I have heard and it is the cheapest of the bunch.
Corrected: MA252 not MC252.
