David,

Agree totally with V-K's reply to you - you will find that the DSP's give you a far better controlled bass - they have the "slam" without the boominess you get in some biiger speakers. But perhaps the biggest impact you will find is on the width of the soundstage (far wider) and clarity.

On the G series - v - 500 series - I auditioned a G08 recently into DSP7000's and to my ears it was harder and brighter than the earlier transports - a view held I know by a number of our fellow hitchikers (but not by others - I'm bound to get shot at dawn for that one !!) If you are thinking of getting rid of your 500, make sure you try the newer models first - you never know, you might find the same as I did.

In the US - have a look at http://www.audiogon.com/ as an alternative to e-bay.

Good hunting
