Stellar Linestage

Even for an oldish geezer such as myself, Wayne Colburn's BA2018 linestage was a breeze to assemble. It performs like a champ: a broad and deep soundstage, excellent detail and a delight to listen to. Many thanks to Wayne and the diyAudio store for making this available!

Excellent preamp!

This is a preamp for us DIYers offered from the mastermind of the PassLabs preamps - Wayne Colburn.
It sounds very detailed combined with a clarity and without harshness. Bass is solid and controlled. I used
TOSHIBA TTA/TTC004B for the outputstage. Drives all my Poweramps (F-5T, BA-3, BA-1, M2X, 50W-SE-Schade)with ease.
Absolutely no noise audible in my combinations. Can also drive headphones (with big BJTs in the outputstage).
PCB is of excellent quality and was delivered very fast. Thanks to the DIYAUDIOSTORE-team!
Build it - enjoy it!

best preamp sofar

been looking for a linestage that fits my M25 (Babelfish) better than BA3FE or other chippy preamps i tried.
this is it! clear sound - not mumpfy, not sharp.
till now i've just made the standard model running on 20VDC. no bigger semis in Q8/10 position.
still looking for a nice housing.
Thank you Wayne!


Love this preamp—I was lucky enough to get a pre release to build (my images are NOT of the final PCB). Clean, clear and detailed—with Aleph J—nice combo I think. Headphones out with a switching jack—YES—and it's great! Check the thread on the DIYAudio forum for build ideas. There's some good info. BUILD THIS PREAMP!


I built the BA-3 and I built the Wayne, both are exceptional. The Wayne has some softer nuances than the BA-3 but both exceptional !!!
One more point to the Wayne for the extreme ease of adjustment ....

Detailed, dynamic, yet smooth.

It took a two or three weeks for some brightness to settle out, then the BAF 2018 became a great sounding preamp. Absolutely silent regarding noise, deep and punchy bass, body in the lower midrange, crisp and clear highs, and great stereo separation. I am mating it Aleph J mono-blocks. I liked the preamp so much I bought another board and parts kit to build one for a friend.

Very nice

Very nice high quality board!!!

Excited to build

Haven’t yet started putting together but enjoying reading (and re-reading) everyone else’s progress and successes. Just getting ready. The boards are beautiful.
