What does "ships within 24/48 hours" mean?

In a nutshell, ships within 24/48 hours basically means that your product will be shipped out or dispatched from our warehouse within 24/48 hours after placing the order. It also indicates that the products are readily available at our warehouse and once we receive your order, we dispatch it out at the earliest either on the same day or the next working day depending on when you’ve placed your order.


What it does not mean:

A lot of our customers assume that it means their order will get delivered to them within 24/48 hours, but that’s not what it means. For an order to reach you, it can take anywhere up to 3-4 business days, depending on which part of India you are placing an order from.

Exquisitely Engineered SRM-400S New DC Amplifier With FET Installed In All Stages

STAX introduces a new semiconductor driver unit SRM-400S, the successor model of SRM-353X. The solid-state amplifier, SRM-400S, exhibits remarkable versatility and excellence. Your appreciation will grow as you progress with your listening session. STAX introduces a new semiconductor driver unit SRM-400S embedded with STAX custom-made low noise DUAL FET installed on First Stage with a FET also installed on Last Stage. The characteristics of right FET and left FET are measured strictly. SRM-400S is an amplifier with FET installed in all stages. In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-400S. The low voltage winding improves the power efficiency and achieves further power saving and better sound quality than the conventional driver units. The complete DC amplifier configuration of the signal circuit includes no coupling condensers.

Japanese Electrostatic Pioneers From 1938

Stax, founded in 1938, is a Japanese company that makes high-end audio equipment. Twenty-two years later, in 1960, Stax released their first electrostatic earspeaker, the Stax SR-1. Over the following thirty-six years, Stax produced a variety of amplification, earspeaker, tonearm, CD player, DAC, phono cartridge and loudspeaker products.

Stax is best known for its electrostatic and electret headphones, which they call earspeakers. Electrostatic headphones work similarly to electrostatic loudspeakers but on a smaller scale. In 1995, fifty-seven years after the company’s foundation, it became insolvent. The company was revived in 1996 as the new STAX company. In December 2011, Chinese loudspeaker manufacturer Edifier announced the acquisition of 100% equity in Stax.

It's ok (for the price)

This is far too expensive for what it delivers. The tiny SRM-252s already gets you into this territory at a fraction of the cost. If the SRM-252s is an 'A', this is an 'A+' (barely).

You do get XLR inputs, though. There are also two earspeakers out. Why would there be such a thing, other than to compare and endlessly quibble about the performance of different types of earspeakers?

It is simply not good value.
