[Linlai™ Global] E-6SN7 with Cary SLP-05 Pre:

Below is review submitted by professional reviewer Robert Grossman (with EnjoytheMusic.com e-zine):
“Larger tubes produce a bigger sound; premium tubes create a higher-quality sound…
I’ve been using LinLai tubes in several amps and preamps over the past five years. I offer some perspectives and listening experiences after recently returning to test and hearing the stock Electro-Harmonix 6SN7 tubes in the Cary SLP-05 preamplifier in comparison to the LinLai Global E-6SN7 tubes.
When I purchased the Cary preamplifier about six months ago, I initially burned it in with the stock Electro-Harmonix tubes for about 200 hours. Upon hearing the beautiful, articulate sound of this preamp design, it was time to try other 6SN7 tubes to explore further sound qualities. My first choice was to try the mid-1950s RCA side-getter tubes, since I had heard from a tube seller who had sold many of them to other Cary equipment owners. These were more powerful and engaging-sounding tubes that presented the music’s low end quite well compared to the stock provided Electro-Harmonix tubes. However, the robust sound of the RCA tubes came at the expense of losing a sweet, balanced midrange. I decided to get a quad of matched Linlai (Global) tubes after two months of using the RCA. The Cary preamp uses six tubes, but I had a pair of Linlai (Global) tubes left over from when I used an Aric Motherload XL preamplifier. Because of the LinLai (Global) tube’s reputation for reliability and longevity, that pair could be repurposed into the 5th and 6th sockets of the Cary preamp. I had successfully used the Linlai (Global) tubes in the Aric preamp to achieve a beautiful, balanced, and rich musical result. Now I figured getting another quad to go with the pair that was here would bring the Cary preamp to life, closer to hearing live musicians.
I am a retired bassoonist and was the principal librarian of The Philadelphia Orchestra for 40 years. My endeavors at home these days in retirement are focused on recreating sound in the most musical ways possible. I continue to collect, clean, grade the vinyl condition, and organize the 20,000 recordings here at home, which has been a lifelong pursuit.
The Linlai Global tubes have gone another step in achieving my goals. Once I seated them and turned on the preamp, their jumbo size really stood out! My eyes were surprised at the authoritative and distinguished look, while my ears took notice of the new and bigger sound. These tubes presented all the usual attributes in the narrative of creating a greater realm of reality. There was a greater sense of depth and fullness in the sound that wasn’t just occurring from simply turning up the volume. The quality of
musical resolution, depth of field, and soundstage were clearer and more realistic. With orchestra records, the musical landscape was larger and more resonant, so the acoustical space of a concert hall could be more clearly reproduced and heard, with a greater sense of body in the space. With chamber music, the individual voices and placement of the musicians were better defined, so the perspective of the two violins, viola, and cello in a string quartet felt present in the room with the soundstage image of the Quad 63 speakers. Listening to my bassoon teacher in the Philadelphia Woodwind Quintet record on Columbia Masterworks ML 5613, Sol Schoenbach stood out more while also blending dynamically with the flute, oboe, clarinet, and French horn. This is because the LinLai tubes enabled the Cary preamplifier to convey details and timbre so accurately that my ears found the sound presentations of musicians I personally know to be more realistic.
I love playing piano recordings and find their presentation to be an extremely important test for hearing the interpretations and techniques of the pianists. What could be simpler and more complex at the same time than properly portraying the size, strength, and dynamic depths of a grand piano? I heard them many times, as concert artists performed with The Philadelphia Orchestra or as they warmed up backstage. In this demo, there was a sense of intimacy and vitality as I listened to my former music director play Mozart’s piano sonatas on the DG 7 LP box set 2720-092. I used to hear Maestro Eschenbach practicing when I went into his studio to deliver scores and pick up music for our rehearsals and concerts. These Linlai (Global) tubes allow me to relax and hear the music better while thinking less about the stereo’s technical and analytical aspects.
It takes high-quality, well-designed, and well-manufactured tubes to bring out the very best in a preamp’s contribution to the important beginning of sound amplification for a music system. I know about sound as a musician who has practiced relentlessly, rehearsed countless times, and performed hundreds of concerts since I was a little kid. I looked up technical information and found that some actual construction and design features for achieving musical results involve tubes with larger glass envelopes and larger plates, which allow electrons to flow more effectively. From correspondence and discussions with Rachel at Grant Fidelity, I can tell she has passion, dedication, and a commitment to providing the finest tubes for her customers. She has helped me gain a better understanding of tube choices and results, expanding the performance levels achieved in my systems over the years as I have changed equipment. Thanks for all the recommendations and for supplying premium-quality tubes.”
