1. From the June 2021 Stereophile:

HiFi by the Pound? From the PrimaLuna ad: "$9k for a 15lb preamp?!
If you want to pay $9,000 for a 15 lb preamp with mediocre parts, that’s your business. If you want to pay 4,699 for a 53lb preamp crafted with the finest exotic parts, that’s our business.

2. HYPSOS by Ferrum
Revolutionary power supply
Linear/switching hybrid design — 100-240V AC in — 5-30VDC out — 6A/60W

HYPSOS comes with one of the two high quality DC power cables fitted with a 5.5 x 2.5mm and a 5.5 x 2.1mm DC plug, to connect to the most commonly used DC inlets. Other DC plugs can be made to order. $995

3. I see MQA technology continues to be licensed. Have there been any rigorous tests?
Radio Paradise, an internet radio station, has signed an exclusive deal with MQA.

4. Need a recordist:
A friend is working on a multilocation recording project, and seeks someone to record one part of it: a calliope in southern New Jersey.
Requirements: ~two hours of music; anticipating two-mike stereo on one side, same on the other, plus a single mike at the end where the drum is located. Recording at 24bit/96k per channel is required. The time frame is within the next two months (sooner is preferable).
Contact me and I can put you in touch with the project manager.
