If you want to only stream, then you could try something totally different and also sell the Gustard to raise some funds. I owned the Gustard X26 Pro and liked the DAC and know how Gustard DACs sound. The following "amp+dac" is $1300 and is pretty good in stock form. Now if you get it modded for $600 by Tweakaudio.com it becomes amazing, especially for the price.
The "totally different" comment is because this is a piece of audio gear that has a digital converter, and amp, and maybe a preamp section, but NO volume control. All it has is a SPDIF input. PeachTree sells a $600 streamer with volume control ability. If you use ROON then it would open of a lot of options to control this device. You eliminate a lot of wires with this unit (a huge sonic bonus).
I sold $15k worth of gear after I got it. Unfortunately, my current speakers need more current than what the GAN1 delivers so I use the GAN1 for my headphones. It is an incredible amp with my uber revealing phones.
My frame of reference for amps are the CODA #16, Benchmark AHB2, KRELL DUO 175XD, Parasound A21+, and many others I have owned. The modded GAN1 is one of the very best.
I have not watched this video yet. It is Mark Levinson’s (the man) new company. He is selling something that is just like the GAN1, with volume control (no remote last I checked).
