I'm thinking of going for one of these when a good used one comes along having seen it at the Bristol show yesterday. I know it's been about for a while but was impressed with sq improvements in the test (I've copied the description of it below from another post). Just wondered if anyone has tried one (or similar) and what the change was with your kit. The test yesterday was good but I only ask others as you only really know once you get it home on your kit where you are used to how much difference (or not) it makes, knowing own hi fi. (I realise I have to demo one first before I buy but am just trying to canvass opinions).
"In the test they were using Swedish Larsen 6.2 speakers with an exposure CD player and exposure intergrated. To give an idea of value for the test, I checked out the Larsen speakers afterwards which are £2k a pair and the exposure amp and CD player were no more than a few thousand each i think. He first started with an IKEA / b and q power block playing a female vocal track for a minute, then plugged in the basic isotek Polaris, £300 I think, and played the same track. It was immediately obvious there was more spaciousness to the sound and a bigger soundstage and this was the main change. Changing to the £1400 Aquarius it sounded like a better amp with more speed of attack and rhythm, more akin to adding a better power supply. Someone commented naim had recommended not using isotek with their amps (but just adding their naim power supplies, kaching...) until a group of naim people had got together and the consensus was some isotek kit does improve sq on top of perhaps adding naim power supplies.
