Single input tube preamp

I own a space tech Labs qa112 preamp and super rectifier and a space tech Labs DAC I bought them all used and have them powered up 24/7 for years now and never have any problems with them. They sound great and are very easy on tubes. 

@dwolek perhaps you should look up true point to point wiring on the diy audio forum. There are no turret boards or terminal strips in true point to point wiring. A lot of old electronics equipment was done this way and lasted longer than most modern electronic equipment.

@mashif  In my search I came across the Quicksilver Line Stage preamp.

This is an excellent preamp. I owned this for a while and it's reliable, sounds great. I wanted to move on from it because I heard preamps based around the 6SN7 tube and I like that sound better. But this is a solid choice, for sure.

Quicksilver has been around for over 40 years. Mike Sanders (owner) is a great guy to deal with. I own that preamp and my only beef is that the gain (18db) is on the high side.

Another brand worth looking into is VanAlstine. My friend is using the 10RB and he likes it very much!

I was going to wait for the new LTA Velo but I found a pre owned MZ2 at a fair price. Hooked it up today and WOW. What a beautiful sound. Thanks for the input.
