LSA Voyager GAN Amplifier

I have had plenty of kit moded over the decades, mostly to the power supplies, internal wiring, or bypass caps. Simple DIY mod is upgrading fuses, which can be a much bigger sonic benefit than many are willing to admit, or now coating the connections with Goop

The stock Voyager sounds really good after I replaced the leading edge muffling stock rubber feet and got better still as I replaced all my 5+ yo machina dynamica springs with these. Outstanding improvement

The mind is indeed a miraculous thing....

What frequency and amplitude vibrations are you trying to damp? What was the spring rate of your old springs versus the new ones? Are they even different? What is the old versus the new damping ratio? Have you checked to see if it is different or for that matter an improvement? How do you know the damping hasn't worsened?

This is why these "tweaks" are nonsense. It's all in your head until you have some objective basis to actually show a change based on reality.

I hear if you smear peanut butter all over your amp it will sound chunkier.

those springs are absolutely ridiculous, no offense.  

@kuribo You are making conclusions about something you have not heard. So you really do not know anything about this specific amp or mods. 

When I say wow factor I do have a subjective baseline. It is my CODA #8 amp. I preferred it to the stock Voyager. It is very easy for me to do comparisons of these 2 amps using ROON streaming, an apples-to-apples comparison. If I did not have the CODA as comparison I would likely have been happy with the stock Voyager.

The Voyager has a bit more detail and clarity over the CODA #8 but I still found the CODA to forcing me to stop and listen. For example, I do remember saying to myself wow I never knew that Jimi Hendrix song was this good, etc.. when played with the CODA (along with a lot more music). I have had this type of reaction with my AHB2's but not when paired with my Thiel CS3.7 floorstanders. The CODA and AHB2 do not sound anything alike.

The king of detail and clarity in my systems is the Benchmark AHB2. So I have another subjective benchmark (lowercase b). The stock Voyager does not reach the levels of the AHB2 on those attributes. Now if after the mods the more powerful Voyager reaches the levels of clarity and detail of my AHB2's. I will have a considerably useful amp for my difficult to drive speakers. Again this "difficult to drive" is a subjective opinion since I am not measuring anything, just listening.

BTW - I am expecting the modded Voyager to not sound like the CODA #8 more like the AHB2. However, that is just a guess.

Like Class-D have with switching frequencies at 600-800khz, like this Icepower has https://ibb.co/5Kj0rcP that has significant feedback, and still has rubbish phase shift measurements(red trace).

I agree. In order to allow the amp to correct phase shift, the feedback has to be more than about 35dB. You either run at least that much or none at all, IMO.
