I own 1.7i. There are still some WAF things you can try.
1) Different amp. Your Brystons are pretty darn good. I switched from Pass Labs to Magtech, and that improved my sound.
2) Speaker cables. Keep the existing amp, the speaker cables could change things.
3) Amp power cable. If you are using a stock cable, then something tuned for high current may make an audible difference.
4) Room treatments. I have a dedicated room, so I use acoustic treatments on the walls and ceiling. Not sure if you can use this, given your description...
