So amir's readings seem to be differnt from stereophils readings/review. Also if your in the market for a preamp this site is not great. According to Amir he only recommends preamps under $1000 and out of the 23 preamps hes reviewed only 4 made the cut... So basically what Amir is saying is don't by hifi unless you want really cheap stuff.
Its an interesting bias that I have noticed. The funny thing is for what he paid for his spectrum analyzer he could have built a killer system. But his hobby is not audio its measurements.
Absolutely not true. I bought the excellent $3000 Benchmark HPA4 based upon Amir's review. Amir recommends well measuring preamps regardless of their price. I think it's fantastic to know I can buy a $600 preamp that will wipe the floor with many other much more expensive preamps. But, by all means, spend more for inferior equipment if that floats your boat.
