I just purchased a Sony STR-DG600 to replace my aging Harman Kardon AVR-65, now I have all the new Dolby/DTS formats like Prologic II, Neo:6 etc...

The volume on the Sony is relatively low compared to the Harman Kardon receivers, so I was thinking about purchasing an external amp...is this ok to do, and which ones would you recommend to use for the Sony brand receiver?

Thank again guys...Your Help is Outstanding!

The Sony seems to have preouts (outputs) for the right and left surround speakers only (other than the sub preout), so the most you could use would be a 2 channel amp. I don't know that there would be much to gain from adding an amp for the surrounds, but maybe someone with more knowledge than I can address that issue.

When you say the volume is relatively low compared to the HK, can you explain in more detail? Are you saying you can't crank it up as much as the HK,or certain speakers are not producing the same results? Have you calibrated the new AVR?

Hi Guys!
Thanks for replying...

Yes, I have auto-calibrated the receiver...but the volume is relatively low compared to the HK, I can't crank it up as much as the HK,The speakers however, are correctly balanced and calibrated...

any advice on what to do next?

I've never been a big fan of Sony receivers, even the ES line which cost a lot more. I know this receiver is fairly affordable, being had for under $300 with some online etailers. HK makes a high-current design that is normally full bandwidth rated and their guts are going to be a lot beefier. So my guess is that since it is one of the entry level surround AVR's from sony, the internals/electronics/amp sections will not perform as well as more expensive models.

Yes, you could add an amp to drive your mains and let the Sony handle the other speakers. However, for what your going to pay for an amp, you might have been better just paying more and get an entry level Denon, HK, etc...

Maybe someone else will have better feedback.

Hi MitchM2006,

I'd second SirQuack's comments about Sony AV receivers and the ES stuff as well. Check the rear panel of your Sony and see if it has an "impedance selector" switch. What speakers are you driving and what is their impedance? If there is a switch, leave it at the 8-ohm setting, even if your speakers are of lower (6 ohm or 4-ohm) impedance. Sony's use current limiting if the switch is set to the lower position, which would mean the receiver is limiting its power output severely. That would explain why you can't turn it up as much.

Regards,

Would you guys please be able to recommend a receiver that auto calibrates, in the same pricerange that I paid for the Sony STR-DG600?

Mitch,

I think most the people here don't think much of auto-calibration. I calibrated my HK AVR 630 manually, using my trusty rat shack spl meter. As it turned out, the factory settings were actually quite close to my calibrated settings.

Since my HK does NOT have Prologic II and NEO:6..etc.., and my Sony reciever DOES....can I connect an external receiver, such as my HK AVR-65 to boost the level of my Sony's reciever, and STILL use the many different surround formats that the Sony has?..if so how do I connect it?

No, but we could all recommend an AVR for the price of the Sony plus the required external amps.
