His ride cymbals were so clear through the QB-9DSD that it was easy to hear not just the sound of stick striking metal, but where on the cymbal it struck. One of the biggest differences between USB cables seems to be their effectiveness at limiting the transmission of RFI along the ground, and in the shielding of power-delivery conductors. Thanks for a very entertaining magazine; one of the true highlights of the month even if most of the reviewed equipment is way out of my reach. For , Ayre has attacked the less expensive end of its lineup, upgrading a trio of older products to MP versions. I understand if you need a moment to compose yourself before reading on.

Recording of January Listening Ayre equipment favors burn-in time, so the first thing I did was hook up the QB-9 to a backup computer and log over hours of continuous use. Changes to the analog audio circuitry and its power supply that improve the audio performance.

On the one hand, the rest of my system has never sounded better. However, in my secondary system, I noted a preference for the Wavelength over both solid-state units.

Soulution — a Swiss amp goes for a Highland fling.

But the problem is that digital audio equipment is still designed by digital audio engineers, traditional engineers, who, if they are using a kHz sampling rate, are going to make their equipment with flat frequency response to 96kHz and then just put a brick-wall filter on it. Given the RFI-radiating engine that is a computer, the transformer-coupled Crimson employs a topology with some inherent advantages.

Recording of November Due to the various taxes, duties, VAT’s, labor costs, et cetera, individual importers set the price for the upgrades in their own countries. There is zero wow and flutter, and the distortion and noise are about an order of magnitude better ie20dB than the best analog tape machines.
