I like BenF, who continuously introduces the low cost gears to support the inexpensive but excellent phones like pro-82 (or others for their diverse applications) that in some sense deviates from standards set by very expensive phones like HD800, T1, He-6, or the like.
I think there should be a pleasant sonic quality which must be independent of the characteristics found in those expensive flag ships.
In some sense, there might be no good or bad phones but there are different phones.
Pro-82 is special for sure and uniqueness in it for excellent vocals / decent bass / speed / transparency with different types like some harmonic density in mids which is not usually found in so-called good and expensive phones.
I think this thread will be continued and encouraged by many, so that some one explores further into some good and new way to find gems which is low cost and buried under the usual perceptions set by those usual/expensive standards driven by the money driven market.
When we consider that the phone technology is the simplest one in electromotive devices so called voice coil motor that are composed of magnets / coils / the polymer cone or membrane for generating acoustic pressure.
The magnet has been rapidly advanced by Neodynium (China has more than 80% production in global) so that the performance increases more than 10 times recent years. Nowadays phones with more than 1 tesla motors are comon which was advertized in some phone like beyerdynamic t1 at their prime time when 1 tesla magnetic density was rare. Also good quality material for sonic cone or membrane can be available way easier than before.
Consequently good phone can be made in lot lower cost than before.
Likewise dac and amp are also the simplest ones with respect to electric circuitry.
In short phones and those asociated techs are simple enough to get good quality product with low costs.
I think those facts above allow us in here enjoy or wait great phone with lot low cost owner ship, and justify this thread in good way.
