Steven,
I had to laugh when I looked at your system, because I have the perfect example of something that seems to make no sense until you really sit down and think about it.
Chris Sommovigo, the famous cable maker, once told me that the key to something as simple in audio as a cable, is complicated. If you take the best wire in the whole world, but have cheap connectors or the connection itself is no good, the wire can't do its job and will be of little benefit. Its job is to take the signal from, let's say the preamp, and pass it along to the power amp.
Case that you can relate to personally, I had my system that had a $5,000.00 Herron tube preamp and $6,000.00 Herron monoblocks. A tube in the preamp went out and through my fault and ignorance, I blew both amps trying to figure out what the problem was.
The rest of my system included a pair of $5,000.00 speakers and an $11,000.00 CD Transport and DAC. The two pairs of interconnects were $5,000.00 Stealth Indra.
I sent my preamp and amps in for repair. Not wanting to be without my music, I pulled out my old preamp and amp: a B&K PT-3 tuner/preamp and B&K ST 1400 Mk 2 amp. What do you think happened when I inserted this $1,300.00 preamp and amp into the slot in place of the $11,000.00 preamp and monoblocks?
I had a sound that I could have easily lived with for years! Why?!?!?!? Because my, and your, inexpensive little B&K preamp and amp had never been heard properly because the cheap connectors that I had on them years ago didn't allow me to hear how good they actually were!
Stealth Indra's at $5,000.00 a set on $1,300.00 worth of preamp and amp, PERPOSTUROUS and INSANE!!!! Or was it? Was it the interconnect's wire, connectors, connection or shielding?
What's cheap? Maybe the question is not so much the cost determining what's cheap, but the quality of the parts making up the speaker, component or cable that determines whether it's cheap, or if it sounds good.
