Jan-Peter, have a question that I can't find in the docs anywhere:
Would the NCore modules in the FA123 (125 @ 4 ohm) be happy with a 2 ohm load? I've seen some threads here suggesting NCore are happy (happier?) with 2 ohm loads, but those threads were discussing modules with higher wattage.
Thanks!

Any updates to preliminary datasheet on Fusions?

Also next week shipping.
Yes, they can run in 2 ohm. However there is a risk the current protection kicks in and if for a too long period too much power the thermal protection.
We will put this on the 'nice to have list'.
Might be, I don't know, easy is not the same for everybody...
Unfortunately we cannot support this.
I have just purchased a phono pre amp (Schiit Mani) but just wondering if anyone has tried to use RIAA Eq with the Hypex DSP and if its possible to use the new Fusion amps as as a turnable pre-amp and avoid the use of a phono pre-amp. This will be the only use for the RCA connectors in the Fusion, so I'm not worried about the filters being applied to say a CD player or similar.
Just a thought, I have seen people implement it with MiniDSP, and lots of back and forth again about IIR and FIR, but keen to know if any Hypex fans know if its possible and also worthwhile.
Thanks again in advance.

Having read the manual (not more) and played around with the software, I'd say: yes, you can make one filter with the RIAA curve additional to the standard filters you will have (that form the main filter in use).
I expect the S/N of the ADC is good enough for the 20 dB loss. You will need a lineair amplifier to create a 2 V RMS line-in signal; from 0,2 mV MC it's gonna be 50-60 dB (mind allowing some overhead for overload).
Then . . you can have the turntable at line level on e.g. the analog RCA, and as soon as that is the only input, the forlter assigned to that input is sepelected, and presto, . . you have a seamless source strategy.
I think the nc400 was a good example of Hypex both being aware of and favorable to the DIY community.
When talking about DIY and being offtopic.. - a question to all of you Hypex knowers: for a big 3-way active system, would a pair of Hypex UCD2K (with Hypex SMPS3K) play nice with 2 big 21" RCF PA woofer together ? (1 amp + 1 woofer per side). Power is not a question, both are heavyweight league but can the UCD2K be called an audiophile-grade amplifier (for bass only) ?
It is definitely technically good enough, but audiophiles are more guided by old wive's tales, superstition and hearsay, rather than rational, technical thinking, so who knows...
You will be surprised how good this combination will sound. There are several pro-audio applications what use with great success this combination. Customer feedback is excellent, very solid and low THD, low frequency reproduction.
I don't think there are any particular long term effects, but at least the ncores are DC coupled, so any DC will show up, amplified, on the output.
