I have run the TLs with V3>SBM-1, m148> SBM1, and V3 alone. The 148 was too warm and lost low-end detail as a result. I really like the V3 alone, and with running the analog outs to the SBM-1. I didn't do it enough to develop an opinion on liking or not liking it based on sound... but logistics-wise, I like the V3 because I don't have to carry a seperate box and power supply.
If you are willing to do it, the m148 > SBM1 with the hypers does sound fabulous.
