All transports are NOT the same

[Sealed]

Since I have gone through 3 sets of opamps in my mod upgrade path here is the difference:

Stock, cheap opamps like OPA2134PA and the cheaper units used in mass market stuff (.80 cents) are slower, less detailed, and produce a soundstage that is more recessed, and dull. when you move up to the OPA2604PA, you are starting to get serious performance, and away from the mass-fi sound, and opacity. This opamp breathes life into a system.

Moving to a superb opamp like the $4.00 BB AD826, the soundstage cleans up dramatically. The image is pushed out and around the speakers, and there is much improved detail. The percieved/audible speed is better, because electrically, it is.

The 826 is such that it is a leap, not a step, but a leap from the cheaper opamps.

There is an obvious difference in the quality of parts used.
