I wanted to add my experience with the Saga. First off this is just my impression. Many of you seem happy with the saga, not trying to take anything away from what. It was partly why I thought I'd give it a try in the first place.
Also I am very happy with my Vali 2. This just for measure.
I tried the Saga in my setup. I ran it with the stock tubes and I must say - I was disappointed. At first I thought that it might need more burn in - I think I gave it a good 15 more hours at least before I started listening in earnest again (family: why is the music playing when you are not listening?) .
I sent it back. I thought it lacked resolution, detail and timbre in comparison to my standard pre (A Funk Studio Pre). I did hear the difference with the tube in the mix, yet it just gave a little more straightforwardness. Not "tuby" by any means (I only mean the "good" type of tuby of course).
Tbh I even preferred the Vali 2 in comparison as a pre. It lacks even more in resolution and detail, yet it yields a nice holographic image, something that is a ton of fun to listen to for a couple of tracks.
Maybe it wasn't a good match. Would have loved to hear the saga with my monos, but they are currently in repair and return window was closing. Just as a means of assesement - I ran it with a nice Linn LK140. It sounds great for it's age with my Funk Pre.
One question: the volume pot on your sagas: doesn't it fully mute music as well if turned all the way down?
