Small room amp and speakers recommendation

In my apt: my kitchen/dining room/game&TV space is approx 12x12, with sloping walls 5' then angled in... I'm using a vintage Pioneer Elite DVD/CD Player  ($50) into a vintage Parasound HCA-75a power amp with volume controls on the back ($250). Add a pair of KEF ONE bookshelf speakers, a Silnote Audio power cord and interconnect - and I' m golden for vocals (especially female), acoustic piano and vibraphone ("Crystal Silence"), what I call Ereathral (Enya, Dead Can Dance) and light jazz and rock... If I feel the ' need ' to really rock out: I add in a Monoprice Integrated amp ($250) with another interconnect  (using the pre-out) for better definition and volume control, and swap out the KEFs for a pair of JBL L25 PRIMA speakers ($450) - and I've got bigger sound... There are so many choices in the vintage/used market - but as a core: I'd start with a PARASOUND HCA -75a or 1000a: good cheap power cheap power you can double up with 2 in mono. I believe the 1st key piece should be your power amp - the piece you will least likely change as you expand/refine your system over time... Ànd Vintage/Used is the way to go...

Tough to say, for sure, but I’ll give it a whirl as my “home office” is the same size in our basement but it has 7’ ceilings.

Belles Aria integrated. 75wpc and has MM phono stage. $2295 new but expect %20 discount.
muscular amp with smooth delivery.

mates well with:

Dynaudio speakers.
Special 40s list for $3k, but can be bought new for $2400.

DH Labs cables do the trick for me. Huge value products.

what about streaming?
you have a DAC?

Weiky, you've received a lot of feedback. What are your thoughts so far?

Take the Parts Express Solstice, add a used 9/10 belles aria, and you have a lot of $$$ for the front end and goodies.  No way to be disappointed in this combo

  Have to admit, Mr. crusty's thoughts on the DIY fest with the Akitika gear makes me want to get out my soldering iron!
