Advice or Experience with Tube Amps: 485's or KT170's?


I am looking at purchasing a new tube amp to match a set of speakers with 95db efficiency. In this particular setup, I don't think 300b's will give the needed power across the spectrum. This has led to looking at 845 and KT170 tube amps. Both seem to be answers to retaining some of the positive sonic characteristics of the 300b but with the advantage of gaining higher wattage power.  I don't know the strengths or weaknesses of each of these, when comparing sonic attributes.  Can anyone offer advice on this?  Here are some models I have found in searching online:

Mastersound Compact 845 Integrated

Audion Black Shadow 2 Mono Blocks 845

Viva Solistino 845 Integrated

Allnic T-2000 KT170 Integrated

Ayon Triton EVO KT170 Integrated

Thanks in advance for any advice or experience with any of these or with the two tubes in question.

As @carlsbad2 mentioned @aricaudio I’ll mention that I own his Super 300B amp. It’s not exactly the data point you are looking for because my speakers are a lot more efficient than yours. I urge you to go to Aric’s website and look at his products. Hand built and point to point wired amplifiers and preamplifiers that are incredible.

Depending on the size of your room and how loud you listen, 8 watts might be all you need. If so, I’d advise to go with an SET of some flavor over push-pull.
