They frequently have ‘Japanese’ tuning which is far from neutral but suites certain genres. They win at linearity from the lower mids through the presence region, have above average resolving ability and as such service all genres of music. They engage in anti-consumer practices such as price creep, product variation, silent revisions, terrible quality control and shoddy customer service. The more attractive your design, the higher the chance that your quality product will succeed! I will write more on these models and the SRA-12S (a very interesting unit indeed) in a separate post. ZMF: Relative newcomer, as they have released several models that have become very popular in recent years. Over the past few years I have squandered my fair share of money on headphones and headphone amplifiers trying to chase a type of sound I formulated in my head (that I never quite reached). There are very few all tube-based units, many of which are cost prohibitive and fewer still employing DHTs.

I still find them largely allergic to electric music, but they impress with jazz and chamber music. Unfortunately these are becoming very difficult to find in good condition and fetch collectors prices. Ultimately I find them to be too expensive for what they are and the approach of using wooden enclosures as a tuning mechanism not ideal, but novel. Also using high-impedance dynamic drivers, and besting the Sennheiser HD600 in several technical areas such as bass extension and cleanliness of transients. I feel that orthodynamic headphones have too many compromises in vital areas of sound and tend to homogenize music more than electrodynamics or electrostatic types. These very early units (1970s) have thicker diaphragms versus the ultra-thin modern models, and trade some transient response for a warmer sound with a bit more heft, a bit more euphony. I had attended a headphone enthusiast meet-up several years ago in which I heard all the modern Stax models, many vintage units, and several expensive electrostatic amplifiers.

Their modern models are all hybrids, either with FET input and triode output or vice versa. These models have been around for ages, can be modified to slightly improve performance past stock and are available at prices anyone can afford. These are supposed to be the ‘most advanced’ headphones, using ultra-thin membranes which are electrically energized to produce sound. People with sensitive skin may experience a stinging sensation while using urea based skin care product and thus are advised against it. Instead of using sticky thread, the gunsmith can also mark AC with a dark charcoal marker, so that the marking gets transferred to the indexing cylinder when the cylinder is rolled on it. Since in offshore partnership models, development teams work from different locations, language, cultural and time differences can make it difficult to coordinate with them. I recently acquired from a friend three vintage Stax models, the SR-3, New SR-3, and SR-5; as well as the SRA-12S integrated earspeaker amplifier/pre-amplifier, which has changed my opinion. So far I have only achieved satisfaction in this area with models from Sennheiser, AudioTechnica, ZMF, and certain vintage Stax (only with un-amplified acoustic material).

From what I can tell, Stax themselves have manufactured a grand total of two amplifiers which were all tube-based from input to output. The product of two groups, vector spaces, or modules is given by the direct product. Product information is a great marketing tool which helps the sales team by providing the updated information. The sales team is the lifeblood of any business organization. What is the core philosophy of the sales team about serving the customers and earning the customer’s trust and brand loyalty? The down side to material removal processes is that certain things can’t be created. However I have formed very strong opinions after several years and the below encapsulates my thoughts (read: biases) on the various types of headphone gear available on the market, broken down by driver type/manufacturer. I am heavily biased to dynamic driver (moving cone) headphones. From what I understand speaking with individuals more experienced with owning electrostatic headphones than I, the real issue with building a ‘good’ electrostatic system is a shortage of ‘good’ electrostatic amplifiers/energizer units. The manufacture of a steel building is an great mixture of engineering, draftsmanship, ingenuity, teamwork, know-how and metal creating manufacturing experience. Making the mould – before a mould can be made you must have a master plate manufactured from metal or polymer, the master plate has the necessary relief (the artwork is raised) to make an impression in the mould.

It is easy to make a lot of money by selling products online. This is a cop-out descriptor I admit, a lot like ‘musical’, it doesn’t mean much by itself. Their most expensive models don’t do much to distinguish from the inexpensive ones. The best models have emphasis on fast transient response and airy but warm sound. See, you don’t have to do all the work when it comes to changing customer buying behaviour? These paired overlaps in measurement use are clarified in this research, which decomposes dimensions of product innovativeness along conceptual lines into distinct product innovativeness, product advantage, and customer familiarity constructs. Chinese, continental, Italian, Spanish, north Indian and south Indian and many more types of delicacies are possible to be found along with variations in the vegetarian and non-vegetarian items. I really don’t want to present myself as any sort of expert, and I try in general to avoid dogmatic thought now more than ever.
