I received a lemon from bestbuy, could've returned it and got the money back, but they didn't have another unit and I thought this was worth trying a warranty service request. They made me send the receiver back to their service center in Syrcayse, NY, with postage all paid for, to and from Kansas City. Apparently they changed the main board and sent back to me in less than 2 weeks. Not bad, considering I was expecting them to get me a brand new one!
Is it a bad thing to have the main board changed, I mean in terms of long term reliability and/or audio quality?
Anyways, I think the time is past to take it back to best buy for returns and I seem to like this one, using it for my home office desktop. I had it initially hooked up to Klipsch R-41M, but didn't like how the speaker performed on the desktop, so got the old sony ss-b1000 gathering dust in my basement and am pleasantly surprised. It's no audiophile speaker, but it sounds much more balanced than the more expensive Klipsch!
So far I've been streaming spotify premium over blueooth, and this receiver has bluetooth 4.2, which seems to support 44.1KHz sampling, and is probably good enough for streaming music.
I am thinking about getting either as an upgrade

https://www.amazon.com/Echo-Link-Stream-stereo-system/dp/B0798DVZCY
Which one would be an ideal upgrade over the bluetooth streaming on this reciever? Echo link has a subwoofer out, supports higher sampling rates, but it's a bit confusing!
Sampling frequency
Sample rates of 44.1, 48.0, 88.2, 96.0, and 192.0 kHz are supported over optical and coaxial digital inputs. Maximum output over optical and coaxial digital is 48 kHz.
includes support for CD-quality (16-bit) and hi-res (up to 24-bit)
Where as this for audio engine
Sample rates
32 – 44.1kHz
Bit depths
16 bit
Generally the reviews seem to favor the audioengine, but specs seem to be a bit better for the echo link. My primary use would be streaming music over wifi.
