Those Tempros had almost zero shell resonance. They were dead as a door nail, to be honest; almost no ring at all in the toms. I had two stencil sets at one point, and they were both inferior sounding to any of my vintage American sets. and much worse sounding than my DWs, which I think are the best drums I have ever owned. I'll probably acquire another stencil set at some point, but only if they're larger sizes and in a cool finish.
Oh, you only had two stencil kits, I got the impression you had more experience with them. That's cool, its your opinion, nothing more.
I think we can point out some realities though:
Vintage MIJ kits CAN sound amazing. Like any drum, if the shell is square, in round, good edges, good heads, tuned up nicely...they can sing. Maybe it was you, and not the drums.
I own MIA, MIE and MIJ kits/snares. My experiences tell me to listen to the drum, not the badge. Yes, in general, the manufacturing of MIA drums back then was of a higher quality. But lets not pretend MIA drums didn't suffer from issues as well. You really think Rogers, Ludwig, etc painted the interiors of their shells because of sound? Lol. Ok.
Despite that, it doesn't stop us from buying them, playing them, and loving them. Again, its the sound, not the badge.
Btw, if you are talking in terms of build "quality", then my 70's Premier B303 kit smokes any kit I own, by far, including my Ludwigs, Rogers, etc. The craftsmanship in the hardware alone is stunning.
I'm not a DW fan. I once bought a $7000.00 kit from them. Waited 9 months for it, and meh. I sold it 6 months later. I'd rather get a LA Camco (which I did), the original, better, and much less money. Some people really fall for John Good's 'wood whisper' shtick. 2000 year old Slovakian river log...(rolls eyes). Hey, if it makes those hobbyist, doctor types smile, good on them.
When I do sessions, I let the engineers pick what they want me to bring, they know my gear well. You would be surprised how many times I get requested to bring my 60's Stewart kit, over my 60's Slingerland kit...tis true. Ears and microphones don't have biases, they don't care what country it came from, the badge on it, etc. They don't lie.
Enjoy whatever you play. These are my opinions, nothing more.
