Excellent Solid State or Hybrid Monoblocks Recommendations

I am interested in staying under 15k for a pair of high performing monoblocks, sold state or hybrid, to acquire. 

My current system is an Aric Audio Motherlode preamp, a Space-Tech super tube rectifier, Teac NT-505 modded dac, outboard clock, Aerial Acoustic 7T modded speakers, ENIGMAcoustics Sopranino supertweeters, Grover Huffman Pharoah biwire speaker cables, Zavfino Silver Dart interconnects, Melco 6TB server, Melco CD transport, Waversa Reference USB filter between the cd transport and server, Waversa Reference LAN filter, Synergistic Research active grounding block, and Synergistic Research Ethernet Switch UEF.

My modded JC1 monoblocks sound heavenly.  However, I am having issues with no sound coming out of 1 channel.  My modded PassLab X250.5 amps sound really good but lack the top end sparkle, air and litheness of the Parasounds JC1s.   I am gonna fire back up my Canary CA-160 modded tube monoblocks but am not wild about the tube maintenance requirements.

So, I seek another pair of monoblocks that excel in clarity, balance across the frequency spectrum but also present upper registers with delicacy, spaciousness, and nice instrument separation.  I am looking at Audio Van Alstine 750 wpc monoblocks and the Thrax black monoblocks up for sale here on Audiogon.  Other suggestions? 

Thanks in advance.
