Finding a Bookshelf for Luxman C900U/M900U

Hi @deep_333
Does the Borresen share sound signature with Scansonic? I used to have the Scansonic MB3.5, the Treble/Mid is good, however the Bass seem not very coherence and a little bit fake to my ears :’(

@darkknight8586 , no, the Borresen is a better designed, better sounding speaker across the board than scansonic.

If you can stretch your budget further than the OP, echoing @yyzsantabarba 's suggestion above, I would suggest the Yamaha NS3000 (10k) or the NS5000 (15k) as well for this kickass Luxman stack.

Marten Parker Duo...they are extraordinary speakers.
The best I've ever listened to
I liked them more than Dynaudio Heritage, Focal Utopia Diablo Evo, B&W 805 D4
Exceptional speakers...

@emilian67 there is also a pair of Marten Duke 2 in my place around $3500

I currently have KEF Reference 1 Meta and they are excellent, very neutral, they reveal the source and amplification. If upstream is bright or warm, you will hear it. They’re chameleon-like, they can be tuned. I have found that they like a strong SS amplifier, the bass improvement and control is very noticeable.

I’ve also had Joseph Audio Pulsar 2 Graphene. Those are also very nice, excellent tonality and detail, but in my set up they were lacking bass and the KEF sound like a full range compared to the pulsars. I would love to find a nice pair of Perspectives though.

I have also owned the C900U/M900U in the past but did not try them with the KEF or Pulsars but they were outstanding components and should pair well with almost anything. 

@agbrace I have the KEF Reference Ones as well, not Meta, an excellent recommendation in this price range. Interesting to hear that you had a chance to compare them with Pulsars and chose the KEF’s. The Pulsars were on my list to try, but happened into a deal on the Ref’s and I love them. 
 

I did hear Operas at AXPONA this year and made a specific note that I liked them. Given the deal the OP has on those, I think it is low risk to give them a try.
