"Just because something has tubes doesn't mean it's the best. I mean, tubes are obviously good, but the circuit of this thing is designed well and it sounds good"

While he acknowledges that tubes can produce excellent sound quality, he thinks that the overall design and circuitry of a gadget is what really determines its performance. Zappa is highlighting the significance of a properly designed circuit in producing excellent sound, rather than entirely depending on making use of tubes. This quote highlights the idea that technology and components are just as excellent as their design and implementation.
