Thank you peng for the input. This is my first outing with Anthem support.... my tech offered to reach out to them, so I just said "yes". I thought it was a simple thing, but your comment is telling me that I should keep my expectation in check.
That's exactly my point, to lower your expectation but I do hope they would give you a straight answer to a simple question. To be fair, I actually asked them more than one question at the time, but after two email follow up, their supervisor promised to call me, but never did so I gave up.
I didn't delete email of this sort and I found it. The questions I asked were the following:
I bought one from XXXXXXXXX today and I have the following questions:
1. They told me they were authorized Anthem dealer and I believed them because they have tons of them in their store. I tried talking to your technical support before I bought it but I could not get ahold of anyone on the phone. Please confirm they are in fact authorized dealer. I found no warranty card in the box and the box'serial number does not match that on the amp. They gave me a silver instead of black so I am bringing in back tomorrow for an exchange. They said not to worry about the serial number on the box not matching, is that true?
2. I noticed there is only one toroidal transformer in the MCA20, can you tell me what size (kVA) it is?
3. The specs says channel separation is 65 dB, that seems very low, is it because it covers a wider frequency range, what would it be at say 1 kHz.
4. What is the damping factor at the lower frequencies, say at <80 Hz? Basically I would like to know the minimum damping factor, at any frequency.
5. What is the total capacity in this amp, would it be 16,400X2=32,800 uF, that's only half of what there is in the Adcom GFA-555 that this amp is replacing. If so, would I be expecting lesser dynamic with this amp due to the lower capacitance?
Thanks,
I am sure none of them should be "trade secrets" that they can't share, yet that seemed to be the case.
Again, I hope you have better luck, and if so please share the info, thank you.
By the way, Denon/Marantz always responded to my questions, including a similar questions about the transformer size for my MM8003, never failed so far.
I questioned them about the transformer VA rating because they always claimed something like:
"MCA amplifiers deliver incredible dynamics thanks to
massive “audiophile approved” conservatively rated power supplies designed with high rail voltages." I have 3 other two channel power amp at the time two of them have transformers that are visibly much larger, the 3rd, the Adcom's looked about the same size as the MCA's and they were about 600 VA rated total, so I thought Anthem claim of "massive" was exaggerated, especially when the capacitance was about half that of the Adcom's.
Regardless, I do like their amps, just won't touch their AVRs/AVPs. Perhaps their support has improved since, and I look forward to hearing back from you if and when you do get a response.
