I just returned from a trip. Not by car. Not by plane. Not by boat. My trip was on a Grado SR225 headphone plugged into a Little Dot I+ fitted with Sylvania GB-408A (nickel plated pins, not gold) vacuum tubes and an LT1364 operation-amplifier.
I have just listened to various pieces of music comparing the Western Electric 408a vacuum tubes Sylvania GB-408A vacuum tubes on the Little Dot I+ headphone amplifier.
Western Electric 408a vacuum tubes
Preliminary comparison of the two vacuum tubes will give the impression that Western Electric 408a vacuum tubes are clearly superior to the Sylvania GB-408A vacuum tubes. The Western Electric 408a vacuum tubes project airy presence and a wide-open sound stage. The sound is precise, transparent and brilliant. The encounter was like a personal Aurora Borealis light show. Instruments dazzled like light shooting across a starry background, changing expressive colors before my ears.
Sylvania GB-408A vacuum tubes
Liquid midrange. It poured into my mind. "Did I just take the blue or the red pill?" I no longer listened to the music. It now possessed me. Transported to another plane of existence, each pluck on string and stroke of bow reverberated into me and sent me farther and farther away. I was no longer looking at a sky. I was transported beyond it. A voyage. Walking across glass. Each resonance felt like steps on fracturing ice. Song became fragile and emotional.
At the end of one song, I thought to myself, “Perhaps I should return to the Western Electric 408a vacuum tubes.” So I put them in and sure enough, a good solid-state like sound returned. Detailed, crisp and quite good.
However, not all headphone amplifiers play well with the Grado SR225 headphone. I often complain about its piercing highs. I have been experimenting with different amplifiers that might tame the highs. (The Meier Corda Headsix that I just sold could do this.) The Little Dot I+ with Western Electric 408a vacuum tubes, every so often the highs of the Grado SR225 would sizzle and the captivating illusion would collapse. Instead of being immersed in music I would find myself propelled into preoccupation of the electronics.
Conclusion
Which tube is the winner for the Grado SR225? That depends on what kind of sound the listener is after. I think most people would prefer the Western Electric 408a vacuum tubes with the Little Dot I+. Both tubes do what they do well. However, with the Grado SR225 it is quite obvious that I prefer Sylvania GB-408A vacuum tubes to Western Electric 408a vacuum tubes. If I want clear dynamic solid-state sound I already have my Ray Samuels Emmeline XP-7. When I want to experience “liquid midrange” I will turn to the Sylvania GB-408A.
