Flagship product to build around

@dekay 

Currently running the entry level Decware  2 watt integrated amp with tubes from the 50's and 60's into Speaker Lab corner horn (khorn clones) using a MHDT Orchid DAC with the 6922 adapter.  It gets loud enough when using a single sub but as you know there's always more.  I'm not using a preamp but have an old Luxman CL35 (for vinyl) and a Schitt Sega + for remote volume if I need it.

The room just works.  it's a big L shape almost 30ft long with a staircase that bisects the bottom of the L with a half wall.  This gives me two good corners 18ft apart.  The inner elbow of the L is two 45% angles creating a non parallel space just behind the listening area about 12 ft from the front wall.    The space is open behind me and to the right with 9ft ceilings.  

I'm currently throwing a blanket over the big screen when I listen which tightens everything up.  

When I bought the speakers I was intending to upgrade them with either the Volti or ALK horn, crossover upgrade but they sounded so good that I'm not sure that's the place to start which is why I asked the question.  

What is a piece that I can build around that will improve what I have today but won't be the weak link as the system evolves?

Cheers,
Dana

Regarding room treatment.  Wouldn't the treatment vary depending on the speakers chosen?

You're probably on the right track to build around an amp but a Class A/B amp and 350 Watts seems more like a boat anchor than a flagship.

For that money I'd probably go with the Coda #16.  Similar power  but the first 100 watts are Class A (up to 300 watts into 4 OHMS).

I would be hard to build around speakers as I'd hate them until I got something to sufficiently drive them but the amp should be purchased with a speaker in mind.

I'm torn about vinyl.  It does sound better but the hassle involved with cleaning, storing and acquiring the music just makes me question my commitment. to the hobby.  I shudder to think  of having to get up and turn the album over every 15 minutes.  I'm sure I have several hundred albums saved from pre CD era  That would be cool to listen to again but my musical tastes have changed since the 80s and finding excellent copies would be pricey.

Thanks.

Another question.  You have suggested using blankets and pillows to get an loose idea of where acoustics should be positioned.

I'm currently using blankets and pillows on bar stools to get them near my listening height.  

Any suggestions of temporary ceiling acoustics that ill allow me to return the room back to a WFA area when the testing is done?  I suspect the ceiling is an issue as it's the largest flat reflecting area in the room.  The floor is carpeted and has the furniture sitting on it and the walls in my listening area aren't parallels  I have a ladder and couch cushions but is that going to even remotely approximate what the acoustic ceiling panels would be able to produce?

So you're saying DAC is the product build around cause I'm cheap and lazy?
