IMO the X-1, as already stated above, will not give you the "bloom" that you are looking for. Mine never did and I really loved the X-1. It was better sounding to me and my audio buds then the SF line 2. As I recall, the SF tube amps did not offer a typical "bloom" sound either. I was using a Pass X-250 in my system and found that a tube preamp added some bloom versus the X-1 and using a tube amp with the X-1 added some bloom. The balance of either combo was different but enjoyable.
Since you already have one combo, I would say you either need to try differnt tubes in the line 3 or change up some cables. I see that you are using the Audience power cord on the X-350. I have one and although I felt it was a great cord for the money, it seemed to add a little hardness to the mids. It was very hard to tell until I tried the Elrod Sig 3 power cord on my X-250. That is when I realized what the X-250 was really capable of sounding like. As Sean states, try a few different cables first to see if you can get your system to sound as you want it to before changing components, because then you may have to deal with additional system matching issues.
Happy Listening.
