The Space Tech Labs DAC was on my consideration list and I've actually heard one at Al's shop. It was very good as is all of his stuff but I wasn't sure I wanted a Tube DAC.
To be honest what sold me on the Mojo was his white paper about DACs. I liked what he said and his explanations correlated with what I was hearing. 45 day return policy, built like a truck in America and it pairs so nicely with the SPT passive preamp and the SPT hybrid tube amp. I'm really happy with the sound.
Speakers on the other hand... not a lot of places in the northwest carry large horn speakers. There is a place that have the Jubilee on display but it's either the room, the electronics driving them or the combination or just the speakers but they don't sound anywhere near as good as they should for the money they're asking and in their listing space a huge step backward from what I'm hearing at home.
