I agree with Polk432 that separates generally perform better than integrated amps, but separates are still bound by ohms law. If your gripe with the SLI-80 was a lack of detail and transparency then separates may be the ticket. If you feel that the SLI-80 lacked drive, dynamics and an ability to control the woofer, the 120S may not resolve the issue.
The SLP-98 can be configured in many ways to suit your particular application. The SLP-98P has a very good moving magnet phono stage. It can also be configured internally with Lundahl step-up transformers to accommodate most MC cartridges. You can also get the SLP-98 directly coupled by by-passing Audio 1 coupling caps. There is also a F1 version which offers upgraded caps, wiring, diodes and some improvements. A fully tricked out Cary SLI-98P F1, MC, DC is extremely desirable.
