Looking for Speaker Input

IMO, the weak link isn't your speakers.  Try looking at the next electronic components upstream of the speakers.  Start with anything with the initials "Luxman."     

What’s your budget ?  The A5 Magico , a great speaker with discount around $21 k 
 Wilson Sabrina x   MBL 120, or 116
the bigger the budget the more choices ,
your dac is  the front end and For sure a weak link vs stand alone dacs , the Bricasti
there are a lot of great dacs  Bricasti,Aqua , and a bunch of others , a dedicated dac is forsure better  then a multi purpose,dac ,CD player , most of the digital technologies in spent elsewhere ,a dedicated dac is always better .

as audioman has stated, the weak link is you front end - the DAC not the speakers.  In our demonstration room we have been playing with DACs for the past month. Recently hooked-up the Sonus Faber Stradivari Homage speakers.  Sounded excellent but even better when the DAC was upgraded.  Big improvement over the preamp and Class A mono blocks.

OP- If you think there is a weak link in the chain you should describe sound and what you don’t like about it. 

Let me throw an alternative into the discussion. I was shocked but I found really good anti vibration feet an anything can make a huge difference. They worked under every piece of electronics I put them especially under my CD drive(it was a brand new machine). They add clarity, detail, transparency and detail. Plus I haven't done it yet but I've heard the same thing under speakers. Good ones aren't cheap but they're far less costly than new speakers.
