Unfortunately the SAS is out of the equation as he doesn't ship overseas.
I've heard the Modwright is lively sounding and I'm afraid it may be similar to the Musical Fidelity which as someone said is very detailed, dynamic and revealing but IMHO lacks a little weight. It's got bass alright, but the mids and highs seem to have more emphasis.
I'm thinking the Juicymusic maybe more of what I'm looking for.
As my TT is very neutral and my speakers are monitors from PMC I'd like to add a little warmth whil ...
I'm fairly confident the Blueberry (or Peach, for that matter) will add the body and warmth that you seek. There will be a noticable improvement in mids and highs as they come into balance for a more organic overall presentation. You will get a bloom that I've never heard SS do. The sound will be less bleached, and more engaging. Emotional connection to the music will be more easily achieved. Palpability, dimensionality and air will all improve. Again, this is my tube bias showing, but it is also based on direct experience with both units (albeit brief with the MF).
The BB slightly leans to the warm, full and round...but in a very good way. Not in any way a vintage, dark and thick "tooooby" sound. But you do know you are listening to tubes. It is still quite transparent, lively and incisive. The bass might be a bit softer and rounder than with your MF, but it will be tuneful and musical, with plenty of detail and articulation.
I am in complete agreement w the 6Moons review. It squarely hits the nail head in its characterization of the BB sound and performance:

There's a popular (and generally accepted) school of thought that says if only one piece is gonna be tubes, make it the preamp. Adherents claim that if done right, it gives you the best of both worlds.
If you get the BB, make sure you roll some tubes. The BB, perhaps more than any other piece of tube gear in my experience, somehow really manages to reveal the inherent characteristics of each tube. Nice feature for "seasoning to taste"! And it doesn't use a truckload of tubes, so not insanely pricey to use good NOS.
