SHORT STORY
I'd say the 494 is the best smaller than a "4/4" tuba available ever that I have played so far... if my memories are correct from other past tuba models i have tried.

SHORT STORY
My recollection of the Miraphone 282 is what a really good "3/4" tuba would play like. Sound wise, it was brighter compared to the Meinl Weston 18 and maybe even other 3/4 sized tubas. It's been years since I've played both tubas, so my memory is a bit fuzzy.
Although, I wonder what I perceive as "brighter" could just be the higher overtones being more resonant... And not actually brighter per say. When comparing the same models to each other and picking the best one of the bunch...
I got to try the Josef Lidl LBB701-4 3/4 BBb tuba this year too. I think I would take the Mraphone 282 over the Lidl 3/4. The Lidl 3/4 BBb is good, but after years of wondering how it would play, it ended just being fine. Good horn, but doesn't stand out as much as I thought it would.
I also tried the Miraphone 494 this past years Army Band Conference. I enjoyed it immensley.
The 494 tuba, in my opinion, is quite efficient. To the point if you play blatty, the tuba will play blatty. The 494, if you ignore the tone and size in front of you, feels like playing a bigger tuba but in a good way. The 494 deosn't "feel" as restrictive as other 3/4 and even a 7/8 tubas do.
Between the 494 and 282, ignoring costs, availability, etc, I'd choose and recommend the 494 every time. If my memories for the 282 are correct. I believe majority of people would be happier to have the 494. I think the 494 sounds great overall too. Actually, I'd say the 494 is the best smaller than a "4/4" tuba available ever... Unless someone spends a fortune on a completely custom Thein...
BUT, just to throw a wrench into this, if you're only going to play and perform solos on a BBb tuba... The sound that the 282 is probably better suited for that singular purpose... Maybe. Miraphone or tuba sellers just needs to bring both models to next year's Army Conference so I can compare them side by side
Side note, I never got to try the Kanstul 3/4 tubas though
Also, I rank the 496 5/4 is the best of the Hagen family. And so far, I would rank the newest Hagen family member, the 3/4 494 Hagen, just below its 5/4 family member. I think the 5/4 is really good, so it's closest runner up, the 494 is also really good too.
