Basis 2500 vs Debut vs 2800


Getting back into analog and was hoping someone had already investigated these models. Is there a significant difference between the 2500 and the Debut, and would I be better off going with the vacuum hold-down of the 2800 instead of the Debut? Any experienced Basis followers out there? Thanks.

I have a 2500 and my friend WD has a 2800V. It's a toss up and trade offs on sonic signatures. I think his has better bass control, but sounds slightly harder than my 2500. It seems that the 2500 is a great value musical price point. Debut costs much more and "may" sound better.
