And what according to you is good "quality"/"caliber" equipment? Examples of each in a chain - source, pre, power or integrated and speakers would be appreciated.
What properties of equipment make them "good"? And, none of the immeasurable/undiscovered qualities/properties that you allude to in your posts please.
Certainly... though you can't seem to ask without some prejudice laced in your question.
No shortage on the affordable speakers side, PSB, pioneer speakers designed by Andrew Jones, Audio engine powered speakers, wharfedale, B&W. havent even scratched the surface.
For electronics Cambridge audio, NAD, Creek, Arcam, Rotel few examples of entry level high-end integrated amps.
For cables Kimber any, with the 4tc and 8tc in particular, audioquest any. And for the love of god, pls dont buy any cables out of china, hong kong, or anywhere in the east. They are all fake.
My best advice, and what I do, is roll your own cables, if you can. Furutech, Kimber, audioquest cables are available in bulk on the site
High End audio, Video & speaker cables from The Cable company. Some of the bulk cables are very good and affordable. Use wonder solder, which you can also get on this site. You can get rcas from Kimber, cardas, audioquest. Again, dont buy anything from hong kong or the east, all fake.
For entry level DACs, audioquest, meridian, rotel, Cambridge audio, Audiolab for a few entry level examples.
Any combination of these suggestions (and Ive left many out great companies) will result in a system where you can start to hear wiring differences.
Last year a friend assembled a low cost system after asking for advice (Cambridge audio dac magic, Cambridge audio integrated amp, sound design speakers (no longer available, sigh). He was using some lamp cord for speaker cables. I brought over some Kimber 8tc speaker wires when I went to hear it the first time. After listening for some time, getting really used to the sound, we switched the speaker cables to the kimbers. He nearly fell off his chair when we repeated the last song we played. He still has those cables and wont give them back.
Guys, I dont know what to tell you. If you arent listening to good caliber equipment you have no idea what you are discussing here. Theres no magic on finding better equipment. Publications like absolute sound, stereophile, hifi vision, many websites review plenty of good affordable gear and high priced gear.
But if your discourse here remains limited to well this equation over here says this and what I read that some else thinks they know over there you really have no idea what you are missing.
And yes, equations and science is not there only because we don't have the right tools / technology to measure it yet for the masses.
I am not an electronics techie so I can't list for you "these 7 things makes a good amp...", I trust my ears after listening to a lot of music (live and reproduced).
A lot of good engineers do know a lot who work for these companies that build high-end equipment.
Read about some of Nelson Pass's work as one example of an engineer who has a long history of building great sounding amps and has many amp designs.
I mentioned Andrew Jones who has a long history of building speakers with companies like KEF, etc...
And for the dense who will cut up what I have typed above with their smartass responses.
I AM ONLY ASKING YOU TO GO LISTEN TO GOOD CALIBER AUDIO SYSTEMS.
After youve done that, you can make up your own mind.
