Grant Fidelity B-283 Tube Buffer: Worthwhile or No

I was also interested in a tube buffer to smooth out SS sound and tried the Yaquin 1 tube buffer. I liked what I heard and the buffer convinced me to dip further into the tube world and get a Mapletree Preamp. I'm really happy with this and certainly recommend that approach. For a few $ you can find out if tubes in the system would do anything for you. If so, you have the choice of stopping there with a buffer or go further and ad atube preamp. I find the tube preamp (with CJ SS power amp) to provide a level of musical satisfaction that has had me listening to my system for many months now with no further desire to futz or change anything.
