Then if you want to improve the audio even more get some HFT and do the speakers and room. This will again be at least as much improvement as you will get from a more expensive component, but for less money, and they never wear out or become obsolete.
Want better still? Start putting everything on Townshend Pods. Huge. Mega.
Only after doing all this should you even begin to consider a component upgrade. Could prove this easily with a demo but you would have to come here for that. https://systems.audiogon.com/systems/8367 Redmond, WA. Welcome any time.
