Rotel RCD971 vs RCD991 - Differences Parts & Sound; Any photos of inside of 971?

dtm1962 · 25th July 2006, 11:49 PM

I just bought a 971 and I have to wait a week before it arrives.

What is the parts differences between the two?

I know that they both use PCM63 (P) for 991.

I know 991 has balance outputs as well.

Do they use the same transport, power supply, black gates PS decoupling?

Is there more power supply circuits in 991?

Anyone have a list of the difference that they can share with me?

Anyone have a photo of a 971 that I can compare to a 991 photo that I have on my computer?

If they are close inside, other than the larger case, then the law of diminishing returns is prevalent and there is more of a profit margin for the 991.

Any info will be appreciated!

Thanks,

I believe the 991 uses a pair of DACs per channel in a balance configuration and is also more heavily built.

Hi dtm1962,

Drop me an email. I have some pictures of the 971 for your reference.

Moin,

the Rotel RCD 991 has OPA2132 & 132 inside.
One PCM63 per channel.
