Any details on the FIR option? How many taps are available? Is there one bank, or is it per channel?

Opinions on Hypex Plate (FusionAMP) Amplifiers?

That's very useful, nice 
However, according to Hypex sales team:
Disappointing
There is the no upgrade path for customers with plate amps which does not have a version 03xx DSP-board installed. It should be as easy as exchanging this part.

FIR capabilities is only supported on Fusionamps that comes with v5.x firmware from the factory. I just inquired, and currently this is true for all Fusionamps that are shipped from Hypex except FA501.

I am a tad confused, are you saying it's best to order the FA501 direct from Hypex to get the latest firmware V5. X?
Is it best to just order from Hypex direct for all Fusion amps?
I am saying that currently FA501 with firmware v5.x is not available from anywhere, including Hypex.
It will be fine to order the amps from anywhere, but in the transition period (while old stock are still out there), you won't know for sure which version you get unless you ask.

It's never good when manufacturers make a significant change to a product without changing its model name/number, but at least they're answering the question for those who have worked out that it might need asking.
Noob question.
Is my understanding correct that if using S/PDIF I connect one amp using the digital input and then use a second connection to the second hypex over the digital out to the in. I then select L speaker preset on one amp and R speaker preset on the other amp to enable 2 channel stereo playback?
TIA

@Lucmor444 Yes, you can set either amp as left or right. Connecting them in the way you described (run left & right to one, then 'daisy-chain' to the other amp), you should also set the first amp as Master, and the daisy-chained amp as slave. This is especially helpful if you intend to use the (optional) remote capability.
If I resample at source to 93750 and use the SPIDF input, will this improve over 44100 input?The sampling rate is set to 93.75kHz instead of one of the more traditional audio rates. This is specifically done to improve the performance of the SRC4382.
An uncommon clock frequency reduces the odds that mix products between the incoming clock and the internal clock fall inside the PLL loop bandwidth of the SRC.
this topic has already been discussed on ASR before:
Why 93.75 kHz sampling rate?
Kii Three apparently use 93.75kHz internal sampling rate . Why such an unusual choice?
No, it won't. In fact, it will make it worse. Since the amp has its own clock domain, it will need to resample anyway (so 93.75 kHz => 93.75 kHz), and then you'll run into exactly the same issue that they were trying to prevent in the first place.
Why resample at all?
Best way to avoid the SRC is to use the analog inputs… which I prefer to do with the FusionAmps.
Looking for further assistance please (that the HFD manual doesn't assist with).
I want to copy an existing DSP file on one FA253 to another FA253. This DSP file is specified in the 'DSP filename' under Device Info in HFD. When I open Filter Design this DSP file does not appear (it is not presented when selecting 'Open' or 'Recent projects' or as an 'Import project') and no filter parameters are present. The option to "save' is also greyed out and cannot be selected (so I can't then use the clone process as described in the manual to copy this DSP file to the other FA253 amp).
I can only assume user error here and again any help would be great!
