I have owned the SV-226 integrated. Wish I never sold it. The tubes in it were in sockets and could be removed. Not sure about their preamps. Sorry to hear about their customer support.
I also owned and be putting up for sale here on AG a Jolida Fusion preamp. It was not noisy, however provided 20dB of gain which was more than I needed. The Jolida people (now Black Ice) were good to work with, reachable via phone and helpful with questions.
