Check this little GaN amp out. Very high value with excellent sound quality. I owned one for about a year based on a recommendation from here on AudioCircle.

I would recommend reading some of the reviews of the mini GaN amp. Here is a sample of reviewer comments:
"the measurements seem to indicate an amplifier that has both design issues and inability to meet specifications. The fact that the company took away the only measurement graph makes it suspect that maybe they had have modified the design and selling something different than what they originally intended. As it is, it is a waste of GaN technology as it brings nothing to the party but high expense.
I can't recommend the Premium Audio Mini GaN 5 amplifier."
"Distortion is fairly high causing SINAD which is the sum of distortion+noise to be worse than a number of budget desktop amplifiers"
"Noise performance by itself is not good either"
"What is not reasonable is high dependence on speaker load when it comes to frequency response"
That last point is important: load dependent frequency response means the amp will change character with the varying load, and will behave differently with different speakers. Most class d amps have solved this issue and have flat response with load, as it should be. This amp has a 25 year old design with a new fet device. Without a design which takes advantage of what a GaN device offers, it's just a pig with lipstick.
