Over the course of the past year, I have incorporated products into my system to address room tuning, resonance control within the equipment and the quality of mains supplying power to individual components.
I was not a novice in respect of mains conditioning and have tried a number of different manufacturers 'solutions' over the last five years, including an IsoTek SubStation and Nordost Thor with Valhalla power cords before arrving at my present 'magic' box, the Vertex Elbrus Point3 balanced power supply which I have lived with since early 2008 and has since been favourable reviewed in the hi fi press.
The Elbrus has two 'unlimited' outlets, one of which supplies power to my CJ Premier 350 power amp. In addition there are three further outlets supplying 230volts balaced power which supply my CD player, preamp and alternatively, my DVD/Digital Surround Controller or turntable power supply.
The Elbrus, as well as being a substantial beast weighing 20Kg, has two Vertex Silver Jaya AC filters built in and alot of jiggery pokery designed to minimise the vibration passed between components and back to the equipment.
Having substituted the Elbrus for the Thor, the benefits include a substantial lowering of the system noise floor and a coherent, full-bodied sound with incredible detail and transparency which was not evident before.
I also found that substituting cheaper MusicWorks ReCoil power cords (£200 each) for the Nordost Valhalla power cords resulted in a much better sound balance and richness to instrument tone without any compression effects or limitation of dynamic range.
The Nordost Thor/Valhalla stuff now resides on the A/V part of the home entertainment system supplying AC to my plasma/Sky+ box, centre channel speaker and sub!
The Elbrus is expensive but the results are very worthwhile in a high-resolution system and I would recommend a home audition to anyone interested in improving the quality of mains feeding the hi fi.
