Mr. Shadow: Very cool system! Kenwood amp, Technics speakers with 15" woofers, I love the look, sound and feel of eighties equipment. The only piece I'd suggest upgrading is the Pioneer turntable. You might want to look at a belt drive with suspended sub-chassis model such as one of these Pro-Ject Debut IIIs I've pictured below. These can be found fitted with an Ortofon cartridge for less than $380 at your friendly neighbourhood stereo shop where the service should also include balancing/aligning the tonearm and cartrudge to exact specifications. Buying a better turntable and cartridge is well worth the expense. You get far more greater improvement in sound quality upgrading a turntable than buying a more expensive amplifier or CD player.
