Tips for warming up Rotel + B&W system?

Get a smooth, warmish fairly high quality interconnect like Music Metre Signature, Harmonic Tech Truthlink, or Luminous Synchestra Sig.

i also heard no bass in any b&w setups.
anything but bass even in the most expencive 'reference' models.

you could move them closer to the wall and you will reinforce mid-bass this way. the lower bass will still be shy.

I would try Van Den Hul carbon fibre interconnects [The First or First Ultimate]Also solid core copper speaker cables.
The lesson?Never buy a system until you have heard it in your room.

I think I am beginning to sound like a locked groove: Look to your room acoustics. What may seem like subtle changes in setup and treatment can have huge effects, well out-distancing anything due to break-in and/or cabling.

The Rotel 1072 is a hard/coarse/very-digital sounding CD Player. This Player has no warmth whatsoever. The Rotel Pre-Amps & Amps aren't quite so bad. I could not get Rotel electronics to sound good with either my N804s or N803s in a room with good acoustics. I did have good success with the top-of-the-line Marantz Players with the Rotel Pre-Amp & Amp. I finally spent the $$$ and bought the Krell SACD Standard + KAV-400xi and it was a hugh difference, completely transformed the B&W Speakers (detail/warmth/natural-sounding/bigger-deeper-soundstage, etc.).
The bottom-line is that regardless of what the Dealers tell you, B&W Speakers need good electronics, more so than most of their competitors. Krell, Classe, Mark Levinson, Musical Fidelity all work very-very-well with your Speakers and as you will see are worth the imvestment.
