LUXMAN L509X VS M700/C700U

I have a Luxman m700u AMP and  with its DAC Luxman DA-06. I have been using my Oppo HA-1 preamp with this equipment.
I have triangle signature delta speakers.

my next step is to either sell M700u and buy L509x or get C700u to complete the paring with M700.
Please comment with experience.

Excellent mini system. Luxman makes all their gear in house in Japan.
OP - any updates on the 38/700-combo?
Well I enjoyed that but M700u was still very bright for my triangles so I now paired with mq88uc and now planning to by amp with 2 mq88uc cl 38uc preamp and analysis plus speaker cables silver apex 
sound sweet non fatiguing 
I am also planning to pair harbeths 30.2 with m700u let’s see 
I was too lazy to read this whole thread, so perhaps the above question has already been answered....However,  a conversation with my local dealer just today happened to answer the question...the 509 stays in class A up to it’s first 17 watts, and after that switches over to A/B. Cheers -Don
OP - sorry if I misunderstand, but are you saying that your're planning to use 2x mq88? As in mono-blocks?
