I've read the specs so I know the differences between JVC's JR-S600 Mk1 and Mk2 receivers - spec-wise. Essentially, the Mk 2 has 10W more power/ch, 0.02% lower harmonic distortion, 5dB lower S/N on the MM input, and it weighs 0.7kg more! I'd like to know from anyone who has owned both receivers what their views are, the two compared. Do they sound different? FM/AM performance? build quality/looks? desirability? Whatever, just your views of the two compared. BTW, in my case my room is only average size and I don't listen at particularly high volumes, so the difference in power and perhaps the distortion figure too (I would think) make little difference. But that doesn't account for other 'un-quoted' differences in circuit design etc. Thanks.
