Ayre QB-9 Twenty Upgrade!
The QB-9 was one of the most successful Ayre products ever. There are thousands of them out in the world, and to many owners, the QB-9 is still their favorite piece of audio gear. As part of our commitment to providing a lifetime of enjoyment from Ayre products, we are releasing an update for the QB-9 with the newest technology from the 8 series. The "Twenty" update for the QB-9 brings it back to the cutting edge of technology, giving QB-9 owners the excitement of discovering their music library all over again!
New QB-9 Twenty Features
We've made a number of innovations since the release of the QB-9. Here is what has been improved with the Twenty update:
Diamond output circuit improves musicality and bass response.
A new JFET differential stage lowers the noise floor.
AyreLock power supply regulation for better rendering of fine musical detail.
New AC noise filtering for improved resolution.
Custom Ayre Asynchronous USB technology further reducing electrical noise in the system.
New ESS DAC chip for improved signal to noise ratio and spacial detail.
Six layer board design for optimal circuit isolation.
Proprietary reclocking to eliminate USB domain jitter.
PCM play back up to 384 kHz
Native DSD capability up to DSD256 (4x)
HDCD decoding
Cost of the upgrade via an authorized Ayre dealer (like me!): $1500
