Install MKII Transformers in your Classic Preamplifier

We can replace the transformers in your Classic Preamplifier with our new MKII Preamplifier transformers. Featuring a 25% larger core you can benefit from the improved level handling and low frequency response of the MKII model

The upgrade is available in either copper or silver versions.

A customer Mr Paul Eros (formerly of TNT-Audio) wrote to us recently following this upgrade:

"I can only describe the upgrade as nothing short of staggering; so much so in fact that I was initially a little unsure as to what was happening.

I have always held the MF Classic in high regard for the neutral way in which it goes about it’s job of attenuating and switching between source signals. With the new transformers installed and burned in what initially struck me was the way in which the frequency envelope is extended at either end of the spectrum. Whilst the bass is definitely blessed with greater definition, extension and texture it’s the treble response that in my system (with valves doing the work) impresses the most. This has perhaps a lot to do with the improved performance in the bass and mid but female vocals are now blessed with the sort of quality that sends shivers running down your spine and has on at least two occasions moved me to tears. Instrumental timbre and texture is also greatly enhanced and stringed instruments in particular have extension, bite and attack without ever stepping over into stridency.

The new transformers also open up the soundstage enabling me to hear deeper into the mix and place instruments more accurately in an enlarged 3 dimensional space. The stage now extends well beyond the boundaries of the speakers in the lateral plane and the depth perspective is now far more pronounced. It’s these perceptions that caused me to question what was going on with the new transformers. If I perceived the original transformers to be unquestionably neutral and able to provide unrivalled levels of transparency and detail were the new ones adding sound effects of their own. I have finally arrived at the conclusion that the new transformers, rather than adding anything, provide new levels of transparency and musical integration over the MkI’s.

I don't know how you've done it nor do I begin to understand the physics behind the theory but what you have is probably the most cost effective and worthwhile upgrade any owner of an original MF classic can make to their system. I would even suggest that at the price you charge for the upgrade it could be considered the deal of the decade….! "
