Have you given any thought to a B&K PT-3? I believe they have been replaced by the PT-5. You should be able to get a new one for around $450 or less? (Retail $595) Another thought. Different spks! I've owned three JM Labs spks.(Chorus 705/707/and an older two-way floorstander, can't recall model # @ the moment, and I've found them to be somewhat bright sounding w/the exception of the Chorus 705. I understand what you're aiming for. Considering your amp, which I've heard others say is warm sounding, MLD is my choice. (Added benefit: Use as headphone amp in the future.)
All good choices however. Good Luck!
