Goodwin's High End

Spectral DMA-500 mono amp

Goodwin's High End is the oldest and most experienced Spectral dealer in the US. We recently celebrated the 34th anniversary of our long association with Spectral and Spectral has become our #1 selling line here in the store. When you hear the sonic purity and sheer naturalness of the current generation of Spectral componentry you will immediately understand why so many people end up choosing to base their system around their components.

When we first heard the production prototype in early July 2017 here at the store we were rather amazed. We thought that we would hear a subtle but noticeable improvement over previous Spectral power amp designs. However this was beyond what we expected. Shortly thereafter we received our production pair and we had a chance to really audition it even more thoroughly. After living with it for months we are very happy to report that in our opinion this is Spectral's first true "Super Amp".

Then in November 2017, Alan Goodwin visited the Spectral factory and had the opportunity to talk extensiverly one-on-one with both Keith Johnson (Chief Designer) and Richard Fryer (President and Project Manager) about what they had acheived with this new amp. Literally this represents a technological breakthrough. With single-sourced custom parts and a unique circuit designed around those custom parts, Spectral has taken the art/science of power amplification design to a whole new level. Never before have we ever heard such a pure and natural expression of our favorite music. There are many very technical aspects to the design, but really all you need to know is that this is a very special amplifier that you simply have to hear to believe! And so you are invited to visit the store, bring your favorite music and audition it for yourself. One listen and you too will understand why we are so excited about this new amplifier!
