Where do I start-amp or speakers ?


While in the midst of downsizing I sold all my gear: Krell monos, Thiel CS6’s, Thiel 2.4’s, EAD Powermaster 2000, Thiel MCS1, etc.
I am now left with a headphone system based on the entry level Schitt headphone amp, Freya preamp,& a very nice Vinyl NIrvana Thorens 125 turntable,
So how’s that working out for you, you ask? Not so well. I need speakers & amp!
 I went from 2900 sq ft. To 1600 sq ft; a 25x24 room to an 18 x 16 room (high 20-24 ft cathedral ceiling, though, at least.)
I’m now on the way to build a new system , one component at a time; Ceiling is 4K per unit. Every time I see a nice amp, then I see a fine pair of speakers. Back and forth. Do I start with an amp or with speakers? Input, input........

I started from ground zero with a set budget and found myself starting with speakers and then amp and preamp. I must say I knew that my dedicated listening room was going to be same for the next 5 years so was comfortable with zeroing in on my speakers. I started with Magnepan 1.7i speakers, ARC REF 5SE preamp, ARC DS450 mono-block amps and lastly my source a Meridian Media Core 200 media streamer.  I knew that I was going to follow my retailers yearly upgrade options on speakers and that I would eventually land a pair of Maggie 20.7's. Now based on the perception that Maggies require so much power my amp choice was truly wrong and eventually I replaced the solid state monos with some PrimaLuna Dialogue Premium HP mono-block tubes and I must say I am musically satisfied. Next purchase will be a turntable as I look to scratch my vinyl itch. Not saying by any means that I did it right but room, listening levels, music preference and speakers were the starting points for me.

A different perspective - your room could be the real problem. 18x16 is almost square (bad) and a ceiling of 20 makes damn near cubic (very bad). The centre ridge might save you, but I wouldn't count on it.

In these circumstances, I would absolutely begin with speakers, Ralph's expertise notwithstanding. Your room effects look to dominate everything else. Consider real room-filling speakers, like the big Magnepans. Run them on $1000 solid state if need be, until you can afford to improve your electronics.

Can you audition somehow? Because that may make all the difference.

Just my opinion.
I would totally change things up. Think about a nice tube integrated and some smallish speakers to pair with it. Speakers with a minimal cross over i.e. Ref 3A. They would usually be more efficient then most. Have some fun here. Sophia Electric amplifiers sound really nice, haven't heard the Jadis gear in a while but have heard good things. I wouldn't buy into the integrated that advertise heavily in TAS and Stereophile. Find a diamond or two in the huge amount of rough. 
Speakers first, then optimize the amp for the speakers. Makes no sense the other way around.
