B&O CD players with datalink are programmed to act like record players with a built in RIAA. That is why it switches the Beomaster to PH. The 3500/4500 CD players are very neat machines with excellent sound. I will be interested to see if you can hear any difference between the speaker cables - B&O cable is surprisingly good and ,when tested by the golden ears at B&O, is as good as any alternative.
Thought as much re the PH tripping.
As for telling the difference between the speaker cables, I have sensitive & trained hearing & can tell the difference, especially with well recorded CD's like Linn or Naim! I've had to turn the bass & treble down, and the sound staging is way better than the B&O cables!!!
Before we get into the "snake oil" arguments re speaker cables, I do draw the line at spending more than 33% of the cost of a system on the cost of the cabling! I think a moderate outlay on a good quality cable will & does bring benefits! Noticed the difference on all my systems! However have been at shows & can't tell the supposed difference between cables costing £1000 & £2000. As for the quality of the original B&O speaker cables, very basic construction, thin, & I doubt if it is OFC! The Atlas stuff was cheap at only £4.50/m, I have used to great success the Bi-wire version for my Denon/Monitor Audio system & that cost £12/m!
All cables supplied by manufacturers are a basic set-you-up cable, even the B&O ones will be done down to a price! Although they may sound better than other even thinner freebies included with other manufactures products, they are still "basic" and can be improved upon!
