This is the first review in my series of Sylvania tube reviews, and it makes sense to start with the best. The Sylvania 6SN7GT Black T-Plates 3-holes “Bad Boys” is a well-known tube where one of the most noticeable sound characteristics is the bass, which is very pronounced. While the low end is not particularly tight or structured, it does go very deep, however, this depth comes with a price.
If you plan to use these in a headphone amp, the bass could be overpowering, but in an amplifier driving speakers, these tubes really kick butt. The top end is very sweet and well extended, while the midrange remains very liquid, as is typical for Sylvania production. It is no surprise that many enthusiasts consider this to be the absolute best of the 6SN7 family.
Final Verdict: Highly Recommended, especially for speaker-based systems where its deep bass and liquid mids can truly shine.
BTW, there is also 2-hole version reviewed on this site here and Gray plates version with 3-holes also reviewed here.
