Several factors come into play when stating value.
OP specifically stated he couldn't DIY, so he has to resort to market solutions.
The internals of the Phoenix are of much higher quality than the other offerings mentioned and for your dollar, you are getting more worth.
Gilmore designs are known to be great, but head amp is not using the same kind of components you could use for DIY and is charging a fair bit because they have to as an American company.
So when it comes down to what you can get for any given price, the phoenix is a pretty good deal from what I have seen. I am looking to buy one myself, but have been checking tons of balanced amps out.
Either amp should sound great though :/ but who knows what topology the OP might prefer more sonically?
Also if the source is ACSS matched it should, theoretically, give it a performance boost that other camps couldn't get.
But this is all just speculative and based on shots of internals and the designs + specs + the impressions of others, I won't claim to have heard any of these amps.
