You're asking a question that has objective and subjective answers. Objectively, there's no doubt that separates will offer better performance. However, I think you're going to have to step higher up the audio chain than Adcom and B&K to have gear obviously superior to your Onkyo reciever. If and when you upgrade source and speakers, you'll also hear greater differences in amplification upgrades. As to whether it is "worth the switch," well that's the subjective part. Only you know your priorities about where disposable income is best spent.
Pre Amp Help
Hi guys. I am wondering if it is worth the switch to a dedicated pre-amp or a pre-amp/tuner. I currently use my Onkyo Integra A/V receiver as the pre-amp/tuner. I have an Arcam 8SE hdcd/cd player, an Adcom GFA-555II amp, and KEF Reference 103/4 loudspeakers. I use Audioquest interconnects and solid Audioquest bi-wire speaker cables. The Integra receiver is better than most, with a pre-out (obviously), and gold-plated rca connections for the cd, pre-amp out, etc. I like the receiver because of the nifty remote, display etc, but I'm wondering if I'm compromising sound quality. There is presently a reasonable B&K pre-amp/tuner on ebay, as well as an Adcom GTP-500. Any strong opinions??
