I can't really hear a big difference


Some of you might think I'm crazy, or deaf...

BUT..

I just got a BAT VK D5SE, used, for a good price. I eagerly set it up, and compared it to my current CD changer (cost me abourt $200), a Sherwood Newcastle CDC 680.

The bass is fuller on the BAT, voices seem a little bit more smooth, but basically it sounds very similar, if not identical in some places to the Sherwood. I mean, it's HARD to hear the difference. The BAT also sounds softer, like the volume is turned down a tad.

My other components are: ML Aerius i, VTL IT 85...

When I upgraded my amp from an NAD 340C to the VTL IT 85, the difference was mind blowing. I mean, HUGE HUGE HUGE. This, costs just as much (even though I bought it used, and the VTL NEW!), and has hardly done much at all!!

Look into your cabling, both the interconnects & AC cords, which may be drastically restricting your end result. A quality source component, when choked via a compromised interface, may not work much better for you than your bargain-level changer.
My experience is the same.

Amps, huge difference
Cables, big difference
Preamps, some difference
CD Player, relatively little difference

Phono is biggest difference of all.
Life is like that. Remember, some folks insist that good CDPs should all sound alike. There's no guarantee that if you spend a lot of money, you will get a much different sound. In fact, you appear to be guilty of ignoring the most basic rule of audio shopping: Try before you buy. That may not always be possible in the used market, but that is one of the risks of the used market.
