TommyBoy,

I suggest you return your unit, unless you figure out how to change your volume in an efficient manner.

Why do you switch from bypass to upsample while you are listening, especially in the middle of the nite? I use bypass with an analog input, and have no reason to switch to upsample.

Daryl,
Thanks for re-checking the Bypass/Upsample levels with a meter. Since somebody else found different levels with their meter: Could you check the levels with the speakers set to anything but Large and L/R? Like LFE only. So we can see what the levels are without the double bass.
thanks.

Actually those that know a little more would disagree.
Many of us have very nice CD players and external DACs where it makes sense to use analog outputs into the 990 using bypass. Yes this "bypasses" the 990 processor but that is exactly what you would want to do. This way you would avoid any extra A/D-D/A conversions in the 990 effectively using it as a PreAmp only.

I'll check again tonight with different settings. I am not getting double bass with the the mains set to large and sub set to L/R+sub. The only time I get double bass is when the sub is set to None.

I could not duplicate the problem TommyBoy and others are having with the difference in volume between Bypass and Upsample. It was always identical. I used both pink noise from a test CD and music. I couldn't hear or see a difference on the meter. I tried all combinations I could think of. I tried:

Mains Sub
Large None
Large LFE Only
Large L/R+Sub
Small Yes

You have to remember that Bypass mode will not send anything to the sub via the sub out on the 990 and Upsample will. This could result in more volume when in Upsample mode. A meter would detect this as more volume but you should be able to tell by ear that there is more bass.

TommyBoy,

I use bypass mode for my CD player (non-SACD, Cal Audio Labs))because I don't want any processing by the 990. That's what bypass mode is for. Why are you using it?

My point is you should return your unit, because you are not happy with it. Life is too short for bad tone!

The 990 has a few quirks that I deal with. The sound for my HT is superlative, when properly set-up.

TommyBoy - It almost seems like you are confusing CD playback with DVD playback. At least you keep referring to decoding two-channel, I guess you could call it decoding but when I hear that term I think more of something like a Dolby or DTS bitream not PCM coming off a redbook CD. You really don't need any fancy processing to play CD's it is just plain ole PCM data.

So yes I really do want to bypass the processor in the 990 for CD playback that is the reason just about all decent Pre/Pros and receivers have a Bypass mode. The 990 even takes bypass a step beyond most processors by offering a digital bypass in addition to the more common analog bypass.

I have done extensive testing between my dedicated two channel DAC, SACD/DVD-A and the 990 DACs with and without upsampling, trust me there is a significant difference between them.
