Not my first foray into the world of Marten but my first with Nintronics. From early short on/off discussions to delivery of a pair of Marten Mingus speakers, I cannot fault how Roger and Simon bent over backwards to be flexible and help me with the purchase. Delivery was a little late on the agreed day but that was okay and didn’t affect, at all, the unloading and set up as whatever time was needed to make sure all was “just so” was never an issue. Customer satisfaction is clearly a priority with these chaps and is probably spot on in this market. On the plus side I was left with a Diablo 333 for a few hours while everyone disappeared for dinner. There is no demo like a home demo! On the minus side, that has now led to another upgrade purchase and slight change in direction from my current integrated Diablo 300 to a Gryphon Pre and power Essence. Just waiting for that and this will be me DONE! Thanks to everyone at Nintronics who helped to make all this possible and who also cooperated with my local dealer, Nick at The Sound Counsel, for the amplifiers which will now be heading north. Recommend Nintronics from my personal experience.
