Quicksilver V4 or Silver 88 advice needed.....

I've compared an older first generation Quicksilver V4 (green LED power switch) and a Quicksilver Silver 70 (blue Led) and am looking to get the best of both worlds....

1. Love the drive and bottom end on the older V4...the drive is simply amazing with my Vandersteen 2ce Sig II speakers.

2. Love the midrange on the Silver 70. It's liquid 3-D.

What combines these two?

....the newer Quicksilver V4 (blue led with newer transformer) or the Silver 88?

Any advice appreciated from the experts out there! Thank you in advance.
