About AS-123:

We came across this versatile device at one of the Hi-Fi shows in China – while we desperately need to tune the system sound to the best to the challenging hotel exhibit rooms. We were simply amazed by what this device can do to the sound on the fly! We now bring worldwide audiophiles this device at great factory direct price and support, to bring your high fidelity sound enjoyment to a whole new level. Let’s also not forget to enjoy a piece of history: having a taste of what ‘Western Electric’ transformer design can do for sound, during the tube glorious days back nearly 100 years ago!

[Analog Sound™] AS-123 Tube Buffer Hi-Fi Tuning Device is a Must-Have tool for high end audio systems to tune the sound to your very own personal liking. 

What does it do?

  • It can adjust source component output gain level (20 steps adjustment), and match impedance sensitivity between pre amp and power amp. 
  • This device can also turn a non-balanced input signal to a TRUE balanced output signal to enhance system sound quality.
  • Additional 0-180 degree phase inversion allows you enjoy early recordings that were made before recording standard came into effect in the 1960s to their intended best sound (some earlier recordings were made phase reversed – see AS-123 manual for a list of music labels).

These functions are fundamental for tweaking a high end audio system to achieve better synergy between components, and providing listener a much more satisfying high fidelity sound, without having to buy & sell the current equipment.

Before you consider to sell and upgrade your current audio components, give this device a try – it might save you big amount and lots of hassle, plus bring you stunning performance!

[Analog Sound™] AS-123 is full-tube device using the legendary Western Electric replica 197A transformer, with 2 x 6K7 and 2 x 6SN7 tube, plus a 5U4/274B rectifier tube. Line Magnetic Foshan has devoted decades to research the legendary Western Electric vintage audio components and now being able to produce ‘replica’ WE Transformers. It also produces its own branded proprietary audio capacitors used in this tube buffer.

 

How to connect AS-123 in audio system: 

It is a line level device, so you can connect it –

  • Between source components (such as CD player, DA converter, phonostage, tape recorder, etc) and pre-amplifier
  • Between source components and an integrated amplifier
  • Between pre-amplifier and power amplifier
  • The closer to the front of signal chain, the more effectiveness will AS-123 be in tweaking sound.
  • It is also very effective to tweak sound when speaker placement limits the sound stage depth and width due to space limitations.
  • Output of AS-123 can be simultaneously connected to additional sub-woofer to build a tube 2.1 system.

 

Buy “authentic custom made for export version”: 

What we provide is an directly-from-factory ‘authentic custom made for export’ version with 4 pairs of RCA inputs + 2 pairs of RCA and 1 pair of XLR output. Transformers are all custom winded for 115V-120V, or 230V-240V to suit your local voltage. Some units on the online grey market has unethical vendors modified the transformers from 230V to 115V – please note those will no longer be Western Electric Replica transformers from Line Magnetic Foshan, and the authentic transformers are the very much soul of this unique product.
