B&W 603s gone; I'm lost down the rabbit hole

Howdy, All.

When I moved to a small apartment a couple weeks ago, I sold my enjoyable old B&W 603 S1s and began looking for used bookshelf speakers at around $600. Now, after bleary nights of research and days of auditioning, I've lost focus.

Should I invest in Totem Mites? Or just buy an inexpensive pair of Paradigm Atom speakers? Or upgrade the receiver but keep my SACD player and…? Or maybe I should just sell it all and start over with something simple, like a Peachtree and a ? In my darkest hours, I want to know if I should just give up and accept my girlfriend’s offer of her old Bose computer speakers.

Any tips or advice would be much appreciated.

My current set-up is…

* Marantz PM 7000 integrated amp (95W, 8ohms)
* twice refurbished (but running surprisingly glitch free) Marantz SA 8001 SACD player
* $100 interconnects and maybe $50 speaker wire

My listening room is also my living, roughly 15’ x 15’ with standard ceilings and essentially wall-to-wall carpet. I can place the speakers anywhere…near a wall.

I listen to jazz 80 percent of the time at a volume just louder than a normal speaking voice, and adore my handful of SACDs, including Ella and Louis and Jazz at the Pawnshop.

My budget is $600. I could wait and save more, I guess.
