Sugden IA-4

I am running Devore 0/93 speakers which are massively forgiving and looking for a Solid State Integrated as a backup amp for a Push-Pull 300B integrated (coming soon).
I listen in a small room so power is a non-issue, but I do like good attack on bass, rich midsized, and a smooth, non-etched sound. My DAC helps in this regard: Lampizator Atlantic TRP with KT66 tubes.
My current integrated is tube-based (Linear Tube Audio Z10 integrated). I am presently considering the Sugden IA-4. Does anyone have any experience with this Sugden?

I'm not familiar with that model but  heard the A21 integrated amp and the Masterclass integrated being played over the Devore 093 , and I was very impressed with both. Beautiful lifelike sound with nothing distracting me from the music.
@roxy54 thanks for the thoughtful and helpful note on the complementarity between Sugden and Devore O/93s. I know they have been exhibited together and am glad to hear that it isn’t simply the audio reviewers who praise the confluence of those two! The IA-4 is the integrated in their masterclass line; just ordered mine, so fingers crossed. Anyhow, it’s just a backup for those sometimes pesky tubes. 💡
I would like to add that the Sugden gear was auditioned against the Line Magnetic 219, which is itself a great integrated, but I would go with the Sugden, and that Masterclass you're getting is a really special piece. Really sounds like music without being soft or syrupy. You're a lucky man. 
Really appreciate this validation! I’m excited to hear it soon - hard time choosing between the Sugden IA-4 and the following:

Pass Labs Int-25
Luxman L550axii
Esoteric F-03A

Looking at measurements and the sensible, conservative, no-nonsense approach to engineering, plus reading responses like yours really helped me make the decision in favor of the Sugden. Thanks @roxy54

It was a revelation to me when I first heard them 3 years ago, because I knew that they were respected in their native land, but...
So many amps that are highly touted turn out to be a disappointment when you finally hear them. I am certain that you won't be disappointed with your choice. I'm jealous!
