hi Dolifant. It is interesting that you had troubles with the Blackbird. From my research that is supposedly a very good match for that arm/table combo. Certainly the 901 is a step up from the Blackbird. But it is also double the cost or close to it.
I do think that you may be short changing your vinyl by using the onboard phono preamp inn the MF A-308. I believe the importance of the phono preamp is quite often underestimated. In my experience it is vitally important. My Wright phono preamp put a bigger smile on my face than any other piece of equipment that I have bought. At the time I bought it, it equaled the value of my TT. The Wright is a very good phono pre for the $$$ and has garnered some good reviews over at audio asylum. However there are probably others in the $2-3K range that will better it. And if you have the $$$, don't hesitate to spend it on a phono preamp. I think you will find it to be a great investmant that may put even more of a smile on your face than you may have previously thought.
