nuoem.com is a site providing service to NuPrime factory and others.
Therefore you are ordering directly from NuPrime, as safe as it can be :).
Products get listed on nuoem.com when they are under clearance, the end of a product lifecycle. Standard warranty coverage and support from Nuprime.

@rustydoglim Thank you! Really appreciate it if you could share your knowledge on the below:
 
Does AVA incorporate similar tech as :
1. Switch-Mode Power Supply (SMPS) technology as IDA-16.
2. Cross-Matrix Array (CMA) capacitor bank

Do the RCA inputs go through the IDA-16 AMP module?

Finally (please forgive me if this is a dumb question) Apart from 200 WPC is the AVA more similar to the IDA-8 than IDA-16?

Thank you for your time.

Would love to know the answer too although my gut says the analog in goes to the IDA16-like amp module directly without the DSP etc - do we need to enable any bypass in the config?

I am guessing for the optical/coax input, it will go to the AV DAC instead of the DAC10 module?

1. SMPS effect is secondary in this case and obviously they are not the same due to different power requirements.
2. Capacitor arrays are also not the same.
RCA inputs have to go through A2D and digital switch before the amp module.

The closes path for HD-AVA to be similar to IDA-16 is from USB input.

Jason, thx ... this was something I wanted to ask for a while. I am guessing the optical/coax also goes via the A/D. That explains why my linux Daphile box via USB sounds much better with my AVA.

No, optical/coaxial is digital, it goes into multi-channel DAC in the AVP section.

Thx, so the only input that goes into the DAC10 DAC is the USB? Wow!

Thank you Jason. How about WiFi (Airplay, DLNA & Miracast)? How are the inputs through these routed into the AMP?

I've been auditioning the IDA-8 on KEF LS50s and really like the sound. Except that the mid-range feels somewhat flat for a few recordings.

Considering that I will be upgrading the speakers to Magnepans 1.7i -Any opinions on whether the HD-AVA would be better or more future proof?

I really don't think that buying a discontinued on-clearance-sale product would classify as 'future proof'.  But on your LS50s you have, perhaps, the one speaker that is reportedly problematic with the 'NuPrime sound' of newer amps (specially the STA-9: https://www.audiocircle.com/index.php?topic=153574.msg1641869#msg1641869).  Perhaps IDA-16 is the safer choice here?  Perhaps an ST-10? (a bit above the current AVA price tag).

Certainly NOT the STA-9 unless you plan on changing speakers right away.

At any rate, your current KEF speakers enjoy wide renown.  So perhaps keep them a while and find the correct matching AMP and then see if you want to upgrade those?

Future proof is a hard question and depends on your needs. Will it sound good? Yes it will. I use an HDAVA with LS50 and its very neutral, much better than the IDA-6 I have (dont have the IDA-8). It has more digital and analog inputs than I will ever need so it is future proof.

What do I miss in the HDAVA? Two things 1) up-conversion (its debatable if it helps in general but I have seen that it does for bad recordings based on my experience with Audirvana+) and 2) I2S input (for connecting stuff like CDT-8.
