Switching a single set of speakers between two amps

I search all of the posts first, and found one discussion about this topic, 4 years ago, but it wasn't exactly the same as my situation, so I am going to bring it up to see if anyone has experience with this.

Right now, I am using my AV system in conjunction with my analog system - I have a Garrard 301/Jelco 750L/Zu Audio 103, feeding a Tavish Adagio, which then rolls into an NAD T187/Classe CA5300, connected to KEF speakers (stereo pair are the LS50s, which might be the biggest bargain in audio -I used to run Maggies - the 3.7i's, which are great speakers but turn out to be wrong for my room - contact me if you want to buy them! - I initially purchased them for a different environment, where they worked great, but they are too large for the room I am in now).

What I want to do - continue to use the NAD/Classe system for A/V and also for surround SACD, but install an integrated tube amp - maybe the Line Magnetics 518- for use with vinyl and tape.  I located one well-reviewed switch - the Beresford TC-7220 - and I wanted to see if anyone has actual experience running two different amps with the same speakers, especially when one of them is a tubed amp.

I have a similar situation, main speakers being vintage custom built Tannoy HPD 315's. To power the HT part of my system, I built Class D Audio amps w/larger power supplies, and two amp modules, for 500 Wpc. They actually  sound so good, they get used 90-95% of the time.

I have, along with a Primare pre-pro, a separate preamp I built from a kit (Transcendent Sounds Grounded Grid) with a few key upgrades in parts, that does everything I need it to do, and very well at that.

So, I run my tubed phono stage into the Grounded Grid, and then into my SET 300B amp, for an all tube system. I use two identical sets of Tempo Electric Big Twist 12 gauge solid-core silver speaker cables, so all I have to do is change cables at the speaker end.

By the way, I also get to use a Garrard 401 TT, Dynavector 501 arm, and Zu Audio 103R cartridge. For me, it's the best of all worlds. Anyway, that's my work-around for a similar scenario.
