I've waited 14 years to comment on my AX-592. In todays used market these units can be purchased anywhere between €150-€250 and this is a steal! My advice is to buy it and use it as a power amp, as it will bring out the very best of any quality preamp! It is also very important to use the B speakers as these have board mounted posts, not the A ones as they are cable linked! It is impossible in todays market to aquire a 2x100W power amplifier of this quality for less than €2000, and it is still doubtful that it will better the 592. The sound of the power amplifier is very modern, super clear and transparent, with a tight, deep and accurate bass, perfect middles, and super smooth and strong highs. However if one uses the AX-592 as a power amplifier here is where dividents are paid for the very high quality parts used and the super efficient dual mono design. The reason for the latter being the preamplifier which is loaded with every imaginable feature, something that comes at a price in the sound quality. The sound is clear, dynamic, balanced and powerful, but nothing exceptional, just a good sound. As an integrated it is build to a high standard and it suprisingly uses very high quality componetents inside, found usually only in high end equipment, if you take a look under the top lid. Not had my other one on test yet to see if its normal as its in a rack and all wired up and didn't want to pull it all apart until the replacement is ready to go in.Bought this new in 2001 for €600 to use in my home cinema after reading many reviews in the press. If its not ok and help with what to change to fix it would be appreciated. If so are my readings acceptable, am I just being paranoid now I can measure the output. I can't find any pot to adjust the channel bias so assume its fixed. Looking at the scope throughout the volume range there is a tiny difference between left and right comparing the trace overlaid with each other. Output at just before clipping of a 1 Kh Sine wave Tone with amp connected to 8 ohm Dummy Load The readings I am getting are not quite right but don't know if its normal or not or am I just being paranoid Today I thought I would do some measurments to check all is well before I replace my other AX-592 that has the common faulty mode selector switch I have done all basic stuff like blowing the dust out and deoxing all the pots and switches and it seems to work fine. I am looking for some advice on my new to me Yamaha AX-592
