Best speakers and cable for Accuphase E-370 amp

Hi guys,

Apologies for writing in English; my spoken German is not bad and I will understand any reply in that language.

Last week I bit the bullet and, after a long search and many demos, bought the Accuphase E 370 amp. It comes as an upgrade to my current system which includes also Audio Analogue Maestro II CD, a Teac UD 501 DAC playing from Synology NAS,and loudspeakers B&W CM9 (first generation). The Accuphase E370 replaced my previous amp Audio Analogue Maestro Settanta which was a fine machine but quite underpowered. My next step would be to replace the Teac DAC with a DAC 50 module for the Accuphase (it is currently unavailable). The CD is quite fine but may also go in the future. The Accuphase is connected to the CD and DAC with XLR cables. The currently used speaker cable is Chord Epic.

Needless to say, the Accuphase is an absolutely incredible machine but it is painfully obvious that it far outclasses the B&W CM9s. This is why I am looking in principle for new loudspeakers to match it. I listen to really all types of music but mainly vocals (e.g. Diana Krall), heavy metal, hard rock, new wave, and pop (yes, I know it's a weird mixture ). The room is approximately 40 square meters but I do not have a lot of space where the speakers are placed. This is why I am looking at smaller speakers (not taller than 110 cm), either floorstanders or standmounters. If they are pretty and available in walnut finish, so much the better (higher WAF). So which speakers would you recommend as possible partners for the Accuphase? I had in mind ATC SCM 40 and the new Q Acoustics Concept 500. Problem is that ATC does not have a distributor in Austria where I am based. I may be able to buy them in the neighbouring countries. I should be able to demo the amp with Q Acoustics soon. I was also thinking about some Dynaudio models (was quite impressed by their sound in the reseant amp search) and even some Focals. Harbeth is often recommended as a good Accuphase match but the design is, well, archaic. I know that it is tough to make a decision without demoing but it may be very hard to get speakers to home or the amp to the studio to demo. My budget is up to 6000 Euro.

Also, which cable do you think will fit this amp/speaker combo? I am tempted to experiment with a new cable for the B&W CM9s but I am almost convinced this will not improve current situation much.

Thanks a lot for any advice and thoughts!
