DIY projects:

20 l sealed-box active three-way speaker, digital-active with MiniDSP PWR-ICE125, SB Acoustics 8" woofer, open-backed CSS 1.7" BMR driver, Vifa tweeter (for show, BMR handles all above 400Hz). Raspberry Pi 3 running Moode tacked to its back, AES/EBU digital-in to the speakers.

Powerfarm: a bank of linear power supplies replacing all wall-warts in the main system. R-core transformers, RCRCRC filtering, LM317 regulation.

Changeling: JFET folded-cascode MC phonostage. Slightly inspired by Vendetta.

KlangWerk: opamp MM/MC phonostage. Input impedance variable between 0 and 100k plus any C value. Gain continuously variable between 30dB and 70dB.

NoHayBanda: headphone amp + line stage, used with one of my PCs.

In the planning stage: really big speaker, sealed-box 2x12" woofer, two open-back 2" BMRs, some nice and tiny tweeter (Hiquphon?), digital-active drive.


Dreams/ambitions:
-JBL M2 with cobbled-together electronics.
-JBL 4367 with existing main system.
