Integrated Amp Recommendation

I have a Musical Fidelity A3.2 integrated amplifier that started making static when the volume is adjusted. The authorized repair shop informs me it needs a complete overhaul -- for $900. I am considering 3 options:

1) Repair it -- the repair shop tells me essentially they don't make them anymore like they used to and this is a great unit that I can get another 10 years out of.

2) Replace it with a Musical Fidelity M5si for $2k or a few hundred less for a factory-refurbished unit.

3) Something else... Rotel 1592? Parasound Halo?

The speakers are B&W 804's. Input is a Naim Uniti media server through a Naim DAC. No vinyl.

Any advice, recommendations and suggestions welcome!

Thanks,

Bill
