I'd split your budget in half.
Half for amplification and half for new speakers.
Ideas for Pre/Power $9000?
Currently need to replace a receiver. I don't have many local options for auditioning. My system consists of the following; Elac Debut F6, Pro-Ject Debut Pro, Pro-Ject S2 stage, NAS and streaming. I listen in a regular ol' family room with no treatments. Mostly like metal genre. Budget is $9k ish.
