What would you upgrade in this system?


I am new to the audiophile world (and to Audiogon), I am on a limited budget (don’t want to spend more than $1000), and I am seeking advice on what I should think about upgrading next.

My room is small (10.5 feet X 10.5 feet) with a very tall ceiling (10-12 feet high). There are some built in bookshelves on one half of one side of the room (to the right of the listening position), and a large window currently covered by blinds on the other side, requiring me to tow in the speakers toward the listening position for the best sound. I can only put my system along the wall that the doorway is on. The room is carpeted. I am probably only about 6-7 feet from the speakers. Given the above and my equipment (described below), where do you think my money would be best spent? BTW, I prefer analog to digital (though I like both), and I listen to various kinds of music, including classical, jazz, hard rock/metal, and electronica. I would prefer getting the most out of my classical recordings in particular.

Here is what I have…..

-Nottingham Horizon SE with Rega RB250 Arm (and Clear Audio Turbo Counterweight)
-Benz Micro MC Gold Cartridge
- CEC 3300R CD player
-CEC Amp3300R integrated amp
-Project Tube Box SE phonostage
-Sound Dynamics 300TI speakers (one pair) on Omnimount 300-24” Stands
-Tara Labs Vector 1 balanced XLR interconnect for CD player to integrated amplifier
-Tara Labs RSC Prime Generation 2 -RCA Interconnects for phonostage and DVD player to integrated amplifier
-TARA Labs/SMA ESP speaker cable (with banana plugs) custom made
-PS Audio Quintet AC conditioner

Very nice system. I agree that the speakers are the weak link, though far from terrible. I am a Maggie owner, love that ribbon. But you can get ribbons elsewhere. The new Carver ribbon sat/sub system could well fit you room dimensions.
Speakers,I would look at one with a first-order crossover or 1st order with none on the mids.This will allow better integration of the sound,over a shorter distance.
Thanks very much for all of the responses. I am leaning toward speakers or a phonostage, but I can't do maggies since I am not in a completely dedicated room. Any more suggestions on phonostages or speakers, even if it costs a little more than a grand?
