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.

Currently have Daedalus Muse but also buying Wolf Von Longa Son Speakers that are 95db.  I am set on not buying 330b's at this point, so I am looking for class A tubes that have more wattage than 8-10 w.  I do not think most 300b's would be adequate, thus the search for something close to the same end results with broader high and low strengths, i.e. more wattage /power.

Thanks for the recommendation.  The LAB12 Integre4 Mk2 Integrated Amplifier now comes outfitted with KT-170 valves and garners some great reviews.  And the price is right.  I have put it on my short list.  I would still like to listen to it side-by-side with an 845 setup like the Viva or Mastersound. But from what I've read, a lot of people on a similar search would apparently be at home and finalized with this Greek amp! Cheers.

Thanks Jerry.  I know the tonal qualities of the 300b are the Holy Grail of tube amps. I would have to test a 300b SET with my speakers as 95db is not always the same from speaker to speaker. It sounds like you recommend an amp/preamp setup to the integrated models.  I will be looking and pondering, thanks.

Thanks for that.  I have been checking out Aric Audio and the Super 211 SET. It looks very good with the build I've been looking for.  The review on 6Moons was thorough and inspiring.  I have not wanted to have to buy a preamp, but the Aric Super 6SN7 Linestage looks like a nice fit as well.  I'm adding this combination to my shortlist.  Would not have found this without you and Carlsbad2. Thanks.  This is what makes this forum so rewarding.  Appreciate you guys.
