On a journey for the last couple of years

I have read with interest the feedback from the forums and enjoy hearing other perspectives. I have upgraded my system significantly and feel I am now chasing the perfect system, which as we all know does not exist. The last decision I need to make is to replace my Aragon mono blocks with new mono blocks.

Current System

SimAudio - 740P Pre Amp

SimAudio 260 D CD Player

SimAudio 310 LP Phono Amp

Project X Turn table with Ortofon Black Quintet

Sonus Faber Olympica 5 with Martin Logan Sub (which I may upgrade once mono blocks tested

I am looking to enhance the low end with more punch, the Aragon's are just not doing it and I am considering two SimAudio 761's, Mcintosh MC611, Audio Research Mono Blocks. 

I will certainly test drive the amps before purchasing. Thank you for reading my post Happy New Year
