If you have any FETs like 2N3819s to hand, you could build a simple common source FET preamp. The component count will be similar to your bipolar design but the input impedance will be much higher. I have no idea if it will actually sound better, but it should do.

Alternatively if you have an opamp like an LM833 or even an LM358 then you could build something with that. There are lots of circuits if you google, some very simple.
