Just wondering....Am I only one building this version? Finishing other projects first but I see many going for SissySit version, not much activity with M25.

I have every intention to build both, but given MOST, (not all) my speakers are fairly easy to drive, I am thinking about starting with Sissy sit version as first build. (As in before M25, way to late for "first" build)

Any other M25 builders out there?

several B. M25 kits sent , but will they end as SissySIT ....... I can't tell ...... I mean - guess

I know that soon I'll have both fully made , as proper and complete amps , of my own!

contrary to earlier ones ....... I never finished my own specimens of Babelfish J , nor Babelfish J2

I have been listening to commercial First Watt M2. Because it has been such a shape shifter for me, I have been playing around with the strictly subjective aspects. At times, it is brilliant in wholistic, organic way but needs to be left on for a while to get this for some reason.

Anyway, with ribbon speakers, M2 works well down to 2.5R. However, it sounds better with 4R ribbon, but really locks in in sound quality at 8-10R using an impedance matching transformer. So at least with my speakers, it just sounds most optimal at the 8 and above impedance level, though it is quite good also at the lower impedances.

Want M2 to sound 'spooky' like VFET, with that special luminescence and gilded emergence from space, while still having the PRAT organic thing of M2? Use a directly heated triode driver/preamp.

I don't know why this would be, but it is special sounding. VFET doesn't need this and can sound 'spooky' on it's own or with a transistor preamp.

Maybe adding the second order harmonics from the tube to the more dynamic sounding, driving third order harmonic from the MOSFETs in M2 does something, but this, or course, is daft speculation with no objective foundation. The particular DHT tube is a tube rectified 26 tube. I would imagine many DHT tube drivers might give a similar result.

This is why I want to attempt my first DIY with the Korg B1 project (aside from it looking like an entry level project even I can tackle). I am curious how the Korg NUTUBE driver will effect the M2 sound compared to my VFET amps/or directly heated triode drivers with M2.

My original intent had been to build the M25 as the Tokin SITs seemed few and far between, but then PRAS appeared and it seemed a no brainer to be able to reproduce something close to the reported magic of the FW SIT3..dB

I have M2 as well and am going for the S.SIT but with CineMags like you. Currently waiting for CineMag to produce a batch of the high nickel versions.
