Nintronics are 'the jewel in the crown' of quality Hi Fi retailers. Upgrading any separates system is fraught with ( potentially costly ) challenges. Roger and Adam have knowledge and experience in abundance. Nothing was too much trouble in looking after this customers requirement. The team at Nintronics only has one objective, namely to ensure their customers receive the products they require and NOT what the store wants to get rid of. The Hi Fi world is littered with 'box shifters' with inadequate knowledge and products that the hard working Hi Fi enthusiast simply doesn't need. Supplying the right system at the right price is their only mantra. For me the Music Fidelity 3i amplifier was my inaugural purchase and will be the heart of my new system. I'm absolutely delighted. If you want professional, knowledgeable and impartial advice then there's only one place to go ... NINTRONICS.
