Zesto Audio has announced their first audio accessory, the Andros Allasso Step Up Transformer. The international debut will take place at the X-FI Audio Show in Holland on September 30th and the US launch will be at the Rocky Mountain Audio Fest in Denver, CO, October 6-8 in exhibit room #7009 at the Marriott Tech Center.

Unlike manystep up transformers (SUT) which are customised to a specific phono cartridge with few adjustments, Zesto Audio’s Allasso has 40 adjustments in Mono and 40 adjustments for your stereo MC cartridge.

Zesto Audio is a company known for their Phonostages. The Allasso is a product cloned from the same gene pool with all the characteristics, components and knowledge that went into those products. Zesto thought that the biggest problem with phonostages is there are never enough inputs, so the Allasso was created.

George Counnas, President and Design Engineer for Zesto Audio told us, “You are now free to roam the cartridge planet!” He goes on to say, “I wanted to design a Step Up Transformer that is very flexible, easy to use and can work on any standard phono preamplifier with a 47K MM input. I designed the Allasso with enough adjustments to tailor it specifically to your cartridge or your next one, and the one after that.”

All the adjustments are easily accessible on the front and can be done “on the fly” without clicks or pops. No maths skills are required, it’s just you and your ears as you freely adjust, listen and find the best match for your cartridge. There are 4 gain settings of 17dB, 21dB, 23dB and 26dB and the step up ratios of 1:4, 1:6, 1:8 and 1:12 with 10 load positions for each setting allowing for 40 adjustments in Stereo and 40 in Mono. The Mono switch is a unique feature which takes one input and sends it to both outputs. Mono cartridge lovers have the added benefit of listening in either the Mono or Stereo.

The Allasso is designed with the highest quality multiple turn ratio MC transformers. This allows you to get the right gain and loading for your cartridge. They are quiet, with extra shielding and large enough with the multiple windings to handle even your high output cartridges. The grounding scheme is designed into the circuitry, binding posts and enclosure. The input ground lift switches help eliminate ground loops, especially in Mono cartridges. The RCA connectors are gold plated with an isolated ground.
