A beautiful sounding machine. Paired with an Aleph J, the sound is detailed, precise, delicate, not bright or harsh. A straightforward build, apart from some SMD shenanigans (gremlins were blamed, but it was all me). Easily sorted with the excellent guidance from forum members. Thanks to all.
There are so many amps and preamps to try, but this one has a origin story and credibility well deserved. It exceeded my expectations which were high! It also got me to finally learn to work with surface mount parts, a good thing 😁
If you are all about learning to build, build with this one and enjoy both the process and the result.
Thank you for sending, the preamp works very well, I'm still working on the power supply, I have a modified salas + 18-18V. Sounds better than DCB1. Powered by F5.
Fabulous ....but those pesky SMD's...Had to buy another board as I was not happy with my slobber job....I got better but wanted to start over....cant wait to fire it up....Thanks Wayne & all folks involved bringing these great products to market for us DIY'ers!
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!
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!
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!
