Deep Cryogenic Treatment of Audio Equipment by Black Rhodium

What is Deep Cryogenic Treatment?

Deep Cryogenic Treatment (DCT) is the process of cooling an object in a low temperature vessel to a very low temperature, typically that of liquid nitrogen at -196oC, keeping the object at that temperature for a period of time and then raising the temperature back to ambient temperature.

The purpose of applying deep Cryogenic Treatment is to improve the properties of the item being treated. In the case of audio cables and other audio equipment, the justification for Deep Cryogenic Treatment is the improvement in sound quality.

Spendor Classic 200Ti gets great review in Hi-Fi News


David Price spends time with the Spendor Classic 200Ti in the October 2019 Issue of Hi-Fi News.


Extract from the Review:

Spendor’s new 200Ti should raise the eyebrows in the high-end loudspeaker market. It’s a great all-rounder with an enjoyable, likeable character that is huge fun to listen to. What’s more, it will slot right into many rooms and systems with ease.”

We definitely recommended buying Hi-Fi News or searching out the review online as it makes for great reading. Better still, why not arrange a demonstration with us at Six Audio.

The 15 most significant loudspeakers of all time

From The Absolute Sound Magazine, Fall 2019 Issue


THE LS3/5A WAS A BBC DESIGN, licensable to any manufacturer. But it was the Rogers version in particular that swept the USA in the late 1970s.

This small two-way (7.5" x 12" x 6.25") offered startlingly realistic vocal reproduction and a remarkably expansive and "boxless" sound picture. With its essentially neutral midband, upper bass bump, and slightly projected treble, it was not entirely flat, and it had no deep bass. But for a whole generation of listeners, it redefined what was possible in small speakers. Some other, larger BBC-influenced designs - the Spendor BC1 first and the Spendor SP1 and SP1/2 and Harbeth Monitor 40 later on - were better transducers overall. But none quite seized the imagination of the U.S. audio public as did the little LS3/5a. With an updated version still in production today, the LS3/5a has stood the test of time as few other speakers have.
