Best Integrated Amp/Preamp with Full 3-Band EQ for Jensen LS-6B Speakers? Budget $3.5K 

Hey everyone, I’m looking for recommendations on an integrated amp or preamp for my setup. I’ve inherited a pair of Jensen LS-6B speakers from my father (90 RMS watts). I want an amp with a 3-band tone control EQ (bass, mids, and treble) for precise tuning. My budget is up to $3,500, and I’m open to both modern and vintage options. I’d also love creative suggestions for pairing a preamp with a compatible amp, if that route makes sense. What models should I consider for bringing out the best in these vintage speakers? Thanks!
