i also found 2nd hand jeff rowland model 8Ti but prices a bit higher than used fpb 300, will 8Ti outperform fpb300?
I believe the Rowland 7 is a magical amplifier. It’s a little dark and soft on top but the inner detail retrieval is outstanding. I had a pair of MKIIIs in the main system for several months this year and was captivated by their (life like) micro dynamics. It’s Strange how a soft amp (like this) can retrieve so much detail. You don’t see that many for sale--for good reason I suspect.

model 7 mk3 and 8Ti both on sales, model 7 mk3 USD5800, 8Ti USD8300, which one better? i thinking maybe model7 mk3 too old, but how is the performance compare with this 2 amps?
I cannot say for sure, but I would suspect that the Model 9 would be the natural competitor for the 7, not the Model 8. The Model 7 holds its own with the Jadis JA-500 in micro dynamics and shear music believability.
when i decided to buy a used jeff rowland 8Ti, another guy offer Plinius SA250 MK IV, it USD1,800 cheaper than jeff rowland, which one too choose?
