Good Receivers for Infinity Kappa 7.1 speakers

luis,

Do you need a multi-channel HT receiver or is a 2-channel stereo receiver OK? If a 2-channel receiver is OK, something like the Nakamichi  TA-4A would be awesome. However, with any vintage receiver they may need servicing or an overhaul to insure long-term reliability.

A better choice might be a more modern integrated amp from Arcam, NAD, Anthem, etc. More power, better sounding, but less features than a receiver (except for the very best receivers). 

luis,

I was not familiar with the Nakamichi AV-10, so I did a bit of research. Based on that, I did not see anything particularly special about the Nak AV-10. I would think that any comparably priced high-end HT receiver would suffice.

However, the Infinity Kappa line of speakers are typically really good sounding speakers and are worthy of better sounding electronics. If you do not plan to power more that 2 channels of speakers (your Kappas), I would suggest you just buy a 2-channel receiver or an integrated amp. Do you need any of the HT features of an HT receiver? Do you need multiple channels of amplification or just 2 channels? Do you use the radio tuner of the receiver? Do you use any of the HT inputs on the receiver? If you don't use those extra channels of amplification or the tuner and HT features of the receiver, why spend money on those features?

If you loved the Nak AV-10 and want another one, just buy one on eBay. I saw them from $200 - $450. Look for a good clean one at a price that fits your budget, and buy it. If you want to try something else, try an Arcam, Rotel or NAD receiver. Better yet, try an integrated amp from one of those companies if you don't need the HT amplification or features. You will probably get better sound.
