The CI Audio preamp gets nice reviews at its price point and Dusty beleives it is better than the Monolithics of before.
That is a nice statement about the MF A300 if it holds its own with that unit in your setup.
As far as the low output cartridges you mentioned, on a basic level I think that either a .25mv or a .40mv can probably be driven just fine by the MC phono setting (60db/100 ohms)in the MF A300.
Using a basic preamp calculator (from the KAB USA website) for those output values, the suggested gain would be 62 db for the Denon 103r, or 58 db for the AT. The MF A300 MC setting is right in the middle @ 60 db.
I realize there are other factors in cartridge/preamp matching but the 60 db MC setting should handle either of those.
I am about 5 db shy of the suggested 42 db for my 2.5mv cartridge as the MM setting is 37 db on the MF A300.
Not ideal, but not bad I guess.
Yes, I would agree that the MF A300 allows detail to shine through, at least with the Dynavector I am breaking in.
The bass is filling out nicely also after about 25 hours of break in.
I guess I was wondering about things like noise floor, soundstage, air, etc.
No doubt one can do better than the MF A300 phono stage-I was just curious as to at what price point one has to go new/used to do so.
I sounds like the sub $500 units would not make a notable difference in your opinion.
