I am mystified over this.
I purchased a pre-owned integrated on audiogon that is from a very well known high end manufacturer, and it is clearly playing louder through the right channel versus left. It actually sounds like the treble is tipped up hot, but very hot, like 5-10db I would guess. I am going to measure this weekend.
Before you start running down a list of old school analog troubleshooting steps, this particular amplifier has an integrated DAC. This problem persists on the integrated dac input as well as the analog inputs. When I switch speakers cables on the amp end from left to right, the problem switches sides. This holds true on all inputs.
This amp is "audiophile" style. There is no dsp, no balance control, no tone controls- nothing that might explain what is going on. So I am thinking it has to be something under the hood.
Has anyone ever encountered anything like this? Any reccs on what else I can try? I purchased from a very reputable seller, so I am not freaking out over getting screwed, and I believe in the far field this may even be tough to detect. But in the near field where I listen from- it is abundantly clear something is wrong. Hoping to find a fix but not optimistic.
If you in fact have a Devialet, it does have tone and balance controls. You need to use the remote to access them and you can view them and change them on the display of the Devialet. Also one can configure EQ in the online configurator.
I would check the volume control and clean it with a deoxidizer or even replace it. If that is not the problem check resistors, capacitors and transistors in the signal path of the right channel of the preamplifier and power amplifier sections.
I noticed that the integrated you listed in your profile uses a dsp that can be used for speaker matching to your amp. This feature is user adjustable and firmware upgradeable, maybe something wonky is going on with it.It's called SAM, speaker active matching and you can download profiles from their website. Maybe reloading a profile would fix your problem.
If it has an analog volume pot there will be some tracking error between the left and right channels especially at lower levels. I would start by measuring and see if the difference between channels depends on the position of the volume control. Also, can you isolate the preamp from the power amp to narrow down where the problem is?
If the unit has a mono switch, I would see how that affects the result. If there is still a channel to channel discrepancy, the unit is at fault.
check the usual things. Switch cables from left to right and see if it follows any changes.
And use an external source and see if it follows that source. Even if you find that it is the DAC it's still a repair issue.
My gut feeling is contact the seller ASAP and keep in contact with him/her. Keep it polite and keep it to business. But be firm.
Best of luck.
Post your findings.
I would send an email to the seller as soon as possible, if you have not already done so. He should work with you to solve the problem.
If he does not want to work with you in fixing the problem,
How did you pay for the amp? PayPal? Credit card? If either one you have buyers protection.
I've seen an open cap do this, but it could be other things depending on the design. If you have tape or preamp out, you could determine if it is in the preamp or amp stage by connecting to another amplifier.
Maybe it is not the right channel being hot, but the left channel playing recessed? Integration does feel better on the left side, but I suppose it is possible.
Geee Who woulda thought?
It's pre-broken and you were Cheated As a simple deduction.
Take it to a shop and have it patched.. Or try for a refund.
Tube or solid state.
Also FWIW, amp topology is A/B, and the dac simply feeds the integrated linestage.
