Why is there so much used gear for sale?
Because people ask silly questions, listen to countless worthless recommendations and purchase based on them or 10 minute showroom demos in an environment totally unlike their own.
A lot of $10k speakers are a joke. Several mentioned here failed on multiple levels either due to bad design, poor setup or electronic mismatch.
The probability of assembling an SoA system schlepping a bag load of CDs all over the countryside is vanishingly small.
One needs 3 diverse tracks to evaluate a system, assuming one knows for what to listen. Mine:
1. Ruby Baby - Donald Fagan. Original CD.
2. Mornin’ - Al Jarreau. Original CD
3. Underture from Tommy. Original CD
Most don’t make it through 2.
Many newer CDs are vastly inferior to the original release. They are digitally processed copies of poor transfers or digitally processed multiple times. Ditto tracks on Tidal. Ditto some audiophile CDs.
Never forget we are building a system. All the research in the world is not worth a 30s listen.
IF the OP is serious, he should make appointments for a system in his total price and parameter range [ total DoReMi, speaker size, integrated/separates, CD/streamer, etc.]. The system should be properly setup as best the shop can make it. The room should be of similar size, layout and treatment to the OPs. If a shop is unwilling to do this for a $40k+ [assuming reasonable system dollar apportionment for $10k speaker] sale, move on. Accept no apologies as to why the sound is sh.tty. Just leave.
IF the OP finds something, he should get an in-home evaluation. Expect to pay return shipping.
Everything else is just wa…..
