I want to upgrade my receiver/amp and am seriously considering both the Marantz PM5004 or the Harman Kardon HK3490. The main reason for the upgrade (from an aging 5.1 Denon receiver) is to produce better, more detailed sound with my vinyl records. I have a great amount of music on my computer that I transfer over to my setero with Apple's airport express, but, like I said, the upgrade is to produce better sound with my vinyl records. I am currently using Pro-ject's debut III with Pro-ject's phono box II.
I would really appreciate your opinions on these 2 machines and also, if you believe this will make a big difference to the sound I get form my current stereo.
Thanks so much
