You did not err. Those kits were made for cutting through the amplified music. That's the point I was making above, "Lots of guys used them at clubs 'cause they cut through the amplification. The explosive pop is what you heard and that does indeed cut through." You did well.
The reason these kits were so successful is precisely why you picked 'em up - they are cheap. For the money, they do an admirable job for certain styles of music and certain playing situations. The sound from those shells is a very focused tone that explodes with immediate presence and is gone...no warmth...no wood. This translates to a 'cheap' tone. That's just how drummers speak. Sorry 'bout that.
The good news - it was made for your situation - harder edged music played loud and relatively fast. Good choice. They are not the warm, woody, resonant shells of a vintage kit. Then again, it would be silly to play modern metal with a Round Badge Gretsch kit.
Sorry if you were led astray by my previous post. I was clarifying the optimum usage for this particular kit. Sounds like you have a perfect situation for these. Glad it worked out for you.
