weak link 1 = lack of subwoofers
Get a Elac Varro DS1000 and use the built-in calibration tool it comes with (very handy tool for all subwoofer noobs).
weak link 2 = lack of power conditioner
Get a Niagara 3000 or 5000
Weak link
Overall, I am happy with my system. Have a minor case of upgradeitis. Wondering where you would upgrade. Speakers KEF reference 3 non meta. Continuum 8 amplifier. T+A dac 8dsd dac/preamp. Innuos pulsar streamer. Wireworld interconnects and speaker wires not sure of model. Room is non treated 15x18. There is carpeting and window treatments.
