I've auditioned the SA-102 in two occasions. One of them, the CD-LAD was used as preamp and the combo was powering the SF Guarneri. I was not particularly impressed. Then I auditioned but with the 8100 (!) as preamp. A friend (who owned the 8100) was looking for an upgrade and had with him also the Jeff Rowland Model 2. Here the result was more convincing, with the 102 delivering dynamics, control and speed that were on a different league of the Model 2 (an amplifier I like, btw). The speakers were the Audio Physic Avanti II - a fairly difficult load (the JR Model 2 clipped in some occasions with the soprano's voice).
I cannot draw a conclusion from these two occasions, but it certainly didn't sound to me as described on TAS ...
I also own a plinius 8150, which I think is still an excellent integrated ... nevertheless, if you go to separates, I don't think it's a good policy to save money on the preamp. I really don't. Don't dismiss the sa-102 until you have auditioned it with the m-16 :o) I only see the 8150 as a short term solution in this context (imho)
