It may have seemed that I was touting the ART7 as the "best" cartridge. I was merely bringing it up as a very very good cartridge for relatively modest cost. I would hazard a guess that it is competitive with others that cost up to $5K, which was the upper limit for the OP, I think. Also, I am resistant to the notion that you always get what you pay for, and nothing more, in audio equipment. I think sometimes very expensive equipment can fall short of one's personal expectations. On the other hand, you can put a modest priced cartridge into a fine tonearm and be very pleasantly surprised. I also keep in my mind that I would be using the potentially $10,000-cartridge in many cases to play used LPs that I bought for $5 to $10 with an unknown prior history. (Yes, I only buy mint used LPs with zero visible blemishes, and I often buy new releases, but still... About a third of my LP collection is made up of records I bought new over the course of time since the mid-60s. The rest is either from the collection of my close friend, who bought all his LPs new, or used LPs that I bought in Tokyo or at various audio shows. I don't buy from eBay or from second hand stores.)
Raul, you cannot really say you've heard THE First Watt amplifier, since there are many different versions with different intended uses. In some cases, he is experimenting and puts out the product for others to critique. As NP says, it's his playground.
Also, I have no doubts that the Etna is good, should be superior to the ART7 based on cost alone.
