High quality amplifier to speaker switch

I use One pair of speakers, Goldenear Triton One.R, for both tv listening and for more serious music-only listening. For music, the system consists of high quality vacuum tube preamp and solid state power amps. For tv, I have a much more modestly priced (and small) class D amp - saving wear and tear on the tubes and expensive stuff.Does anyone have a recommendation for a switch box to switch between the 2 amps to the same speakers? I would like there to be almost no sound quality degradation.
I know there are some old posts on this, but have not seen a definitive recommendation.

Thanks. I actually made my own switches using toggle switches and Kimber speaker cable. I can’t detect any sound degradation, but they wouldn’t be suitable for tube amps.
To be safe, I only switch when the amps are off.

Thanks for the Amazon link. I may order it and compare to my homemade switch. I notice that to protect the amps it has an internal load resistor across the terminals. Might affect the SQ or amplifier performance somewhat. Seems like a useful device nevertheless.

Here is another option.I bought one in 2017 and have had no issues   https://www.amazon.com/TC-7220-Amplifier-Selector-Comparator-Crossover/dp/B00LNOAGZQ/ref=sr_1_2?dchild=1&keywords=tc+amp+speaker&qid=1591892816&s=electronics&sr=1-2

Looks like another nice alternative. Cant be used with vacuum tube amps however. So, one has to be sure to keep amps off when switching, as a precaution. Just like my handmade switches.
Thanks for the tip.
