So, I found a great deal on the Eat Petit and as good as my DS2 sounds with the Baldwin 1960 tubes, I sold it. The Petit with the stock tubes is very good. A little less grain and a slightly larger soundstage than the ds2, but it just didn’t have the rich tonality of the ds2 with the Baldwin 1960 tubes that became so addictive. So, I put those tubes in the Petit and it was better, but didn’t sound quite the same as they did in the ds2. Too much body and that clouded the lower midrange area a bit. Tonality was still excellent though and almost as good as they sounded like in the ds2. I had a pair of 1959 Baldwins that were not quite as good when I had tried them in the ds2. A little too much upper midrange drive. So, I decided to try them in the Petit. WOW! Perfection! These tubes were made for this phono pre. Outstanding tonality that even my $4k phono preamp using a variety of nos tubes couldn’t match. It’s like the 1960 Baldwins were sounding when used in the ds2, but only with a bit less grain, larger soundstage, less congestion and a bit smoother sounding overall. Along with the tonality, the Petit and the 1959 tubes still have excellent dynamics, soundstage and bite. Deep and powerful bass and a sweet top end that is fully extended. I then tried some nos Ei tubes than are said to be identical looking and sounding as NOS Telefunken smooth plates.They sounded great too, but just didn’t have that rich tonality of the 1959 Baldwins. No wow factor, but nothing to complain about either. Also tried 4 different current production tubes, to include Gold Lions. Gold lions were best of the lot but couldn’t hold a candle to the Baldwins. If you really want to experience what the Petit is capable of, do yourself a favor and grab a pair of the 1959 Baldwins. You can find these on eBay for around $100 a pair or so. So worth it! *Note..my system audio is professionally calibrated and is very neutral, thus letting the tubes do most of the talking without much influence from improper eq and bright/warm speakers.
