I started a new project to build another preamp. I very much like my Bottlehead Quickie, but it has only two inputs and having to change cables to listen to another source is not really great.
Since I was very satisfied with Bob Latino’s VTA ST70 power amp, I decided to go with Tubes4Hifi’s SP14 kit.
I ordered a custom top plate in order to have proper labels for my sources. I also added optional Mundorf silver PIO output coupling caps and an input selector relay board.
The ordering process was flawless, friendly and professional. Shipment arrived on my doorstep after only 5 days. Not bad from the US west coast to Switzerland. Everything was well packed and in mint condition.
I am trying another attempt with Betsy. This time with helper woofers, a DSP acting as a crossover and equalizer and two stereo amps.
The amp is mostly finished and playing nicely. On the last mile I needed a bit of support from Bob Latino. Bob was very kind to support me and promptly replied to my email inquiries.
Here are lots of pictures along the building process. Read more…
