New system/room, upgrade amp or preamp first?


Hi all! This is my first post here but I've been an active A'gon'er for many years.

I recently built myself a listening room in the basement. Nothing too exotic in terms of the actual room construction, but I do have 4 OC703 acoustic panels on the wall for front wall reflections and for first reflections. I had a friend build cabinets and I did the crossovers and assembly of Troels Graven's ScanSpeak 3-way Discovery monitors. Just got them done yesterday, they sound very good but need a while to break-in.

I am currently using Jriver set to DoP, out via USB to a Schiit Loki DAC, then on to a Marantz SR-685 5.1 receiver acting as a preamp, and finally on to a B&K AV5000 5.1 separate amp (5 x 105), obviously only using two of those channels. I have the sub out of the Marantz y'd and connecting to two BIC F12's, used only to fill in the lowend. They aren't the most musical subs obviously but they do a fine job to my ears for 45-50Hz and below. They provide a satisfying weight to the sound without dominating the room.

So, I'm pretty OK with the DAC and source. I'm basically using two repurposed home theater components so those are next on my list to upgrade. The room is small, 13 x 10 (speakers are 82" apart, my chair is 82" back from the center point, about 3' from the back wall). I have kicked around an integrated amp but I do prefer separates if I'm being honest. If I have a $1500 budget for ONE component, what should I be looking at first - addressing the AVR-turned-preamp, or the B&K amplifier? The item not chosen for upgrade at this point will be addressed in another 2-3 months.

It's tough to judge a system with such new speakers but so far, the sound is well-dimensioned for both width and depth, though depth is a bit shallow. Voicing is wonderful, thanks in part to the 4" ScanSpeak midrange (wired out of phase with the woofer and tweet).

My listening tastes are varied but primarily I prefer Rock, Metal, and am starting to get more into blues and jazz. I do some orchestral stuff here and there as well as instrumental concerts (violins and piano). Any and all opinions are welcome, I can clarify whatever is necessary. Thanks!

i've always felt that a very good pre-amp is the soul of a system and mandatory to get right. There are others who feel differently. I'd say get a good tube pre-amp first although if you only have one source another good option would be a good passive like the Lightspeed which is only $500 new and then you can get a new amp sooner.
I would purchase the preamp 1st. I believe that would make the greatest upgrade given what you are using now is a HT processor. I own a Jolida Fusion tube pre and am happy with it driving a SS BEL 1001 MK5 amp. How demanding are your speakers for power?

the pre-amp is the heart-and-soul of any system. Start here and then proceed forward w/ other components/gear. Keep me posted and Happy Listening!
Thanks everyone! We are on the same page, in fact I was eyeing an Arcam FMJ-C31 in the classifieds just a few minutes ago. It has everything I need and would at least get me into a more proper piece of kit for my purposes. I do not intend to start at the top, certainly, and $650 would definitely fit within my budget. With that said, I'll take a look for some other options and keep everyone posted. Mesch - the specs I have from the DIY site I built these from lists them as about 87dB sensitivity 1w/1m so... fairly hungry I'd say. I make up for that somewhat in that I have a pretty small space to work with at the moment.
