Amp recommendation and setup advice please

The Audio-GD site is legit and you have to order direct from China.  I have not ordered any of their items, but many others have and you can search the forums if you want.

The NFB-29.28 is offered in two version:

Version 1: 100-120V  AC 50/60 Hz

Version 2:  220-240V  AC 50/60 Hz

You need to pick the one that matches your local AC voltage. (You need to determine this on your own)

Big Sur Audioquest RCA cables – you just need to determine the length based on how far away the speakers are.

Monitor Audio Silver 10 retail for a pair is £2110 /  $2800 USD

That Oak version on ebay is a nice one and a good price.

The PS Audio Nuwave Phono retail new price is currently about £750 / $999 USD because PS Audio is discounting it almost 50% off.  They are discontinuing the model.  That ebay one is £600 (cheaper), so it’s up to you if it’s worth saving a little money.

That Hegel 200 on ebay is used. It was original retail for £3313 /  $4400 USD.

Here is a better place to buy Gustard if you are interested.  It is rarely on the used market. Make sure to get the USB version:

If you have a laptop, you do not need a USB card.  I would try the laptop out first and see if the sound is good enough for you.  If not, you can look at getting a USB Reclocker such as the Wyred 4 Sound Recovery.  Or buy a Windows PC Desktop and an audiophile USB card, but I would try the laptop out first.

JRiver is media player software that can be used to play all different types of media and sound files:

oh, to follow up on a couple questions:

Here is a good review and discussion of the Audio-GD NFB-28 (which is exactly the same as the NFB-29 except it has XLR inputs/outputs, which you do not need for TV):

In my opinion, the Gustard is a really excellent DAC for what you pay for it.  I don't think you will get better unless you spend a lot more (like twice as much or more).  Here is a 12 page discussion on the Gustard X20 pro:

Hope this gives you a little better feeling about these products.

I came across this thread talking about the NFB 29 (which is what you are considering):

https://www.head-fi.org/threads/audio-gd-nfb-29-single-ended-master-race-lol.732157/

Interestingly enough, he is using it through some AirMotiv speakers! lol.  Lot's of good feedback on this NFB 29.  One of the comments that stood out to me:

The nfb11 has some harshness to it in the treble regions that the nfb29 doesn't have... The 29 is more dynamic, more detailed and overall better. Much bigger sound stage, much better separation and imaging.

Though, if you spend more you get something better, obviously.

If you want powered monitors, I actually use Yamaha HS80m monitors for my computer speakers. They are actually not bad. There are a couple used on UK Ebay:

https://www.ebay.co.uk/itm/Yamaha-HS80M-studio-near-field-reference-monitors-PAIRED-BOXED-free-stands/172900963242?hash=item2841b353aa:g:bAcAAOSwEvhZ0k1p

https://www.ebay.co.uk/itm/Yamaha-HS80M-Powered-Monitor-Speakers-PAIR-In-Boxes-WITH-FREE-STANDS/253206255141?hash=item3af444d625:g:w8EAAOSwH4xZ4IPA

Or you can try to find the newer Yamaha HS8 monitors, but will be even more than the Emotivas. Not sure if these will be better than the Emotiva. Emotiva has a lot more power and will probably be more laid back sounding than the Yamaha. The Yamaha are very neutral, but also very revealing. They have a larger 8" woofer so they would play a lot lower than either of the Emotiva monitors.
