You've got a very nice system there - it is indeed simple and yet elegant in a practical sort of way.
The Cayin is a really nice sounding amp and great value for money. Paired with the Tylers you should have plenty of detail with just the right amount of warmth. It looks like you've got about 2.5 - 3' or so of space from the speakers to the back wall and with the shelving acting as a natural diffuser of sorts added to the corner diffusers/traps, the imaging must be very nice indeed.
Your rig is a perfect example that one need not spend a fortune for good sound.
Cheers,
