You two really need to update your semiconductor knowledge.

Pros for BJT:
"BJT’s at the same physical dimensions and price can usually give you a lot higher speed, as they have very little input capacitance.
BJT’s can give you a lot higher gain. Just take a bunch of components and compare them, and you’ll find the BJT’s give you better gain characteristics and therefore require fewer gain stages.
BJT amplifier stages are much more linear than MOSFET amplifier stages, as the gain doesn’t depend on the bias voltage. This gives better fidelity.
BJT’s are capable of handling higher output currents for signal outputs and can have lower output impedance. In amplifiers intended to drive a low input impedance load or deliver significant amounts of power, this is a huge advantage. Many of the highest quality op amps are made with a BiCMOS process using a BJT pair for the output buffer stage."
Cons for MOSFET:
"Not as high of fidelity as BJT, since the gain will vary slightly as you increase the input voltage (that is, it will generate some very weak harmonics).
Input capacitance. The higher the gain, the greater the input capacitance thanks to the Miller effect.
Can’t drive a low-impedance load very well.
Low gain per part, which often means more amplification stages are necessary for higher gain, even when using advanced design techniques. Each amplification stage adds noise -- that is, you can never, ever get a better signal-to-noise ratio at the output than at the input."
I believe the OP has everything he needs, and doesn’t need the BS from the F5/Mosfet lovers, which I’ve heard and are great amps, if used within their comfort zone with preamps with high’ish gain and speakers not too low in EPDR load impedance’s and moderately efficient, because of wattage limitations.
Hope you got everything you needed bubba12
