Hello

Perfect item, fine musical restitution.
After about 35 hours of running in.
Works well in my mc275 McIntosh
I fully enjoy the music
Thank you for quality items delivery!

This particular ECC82 is a rarity for my small collection. Sounds absolutely delicious in my tube DAC. A noticeable change in soundstage and the decay of tones, especially string instruments and piano included in that is phenomenal. The tone feathers off in an sweet infinite way preserving every detail possible. Soundlumia has great great service, incredible packaging and care taken. Boutique and finesse. Very knowledgeable.

Purchased this pair for use as a backup set. That should say it all.
Sound great in my DAC. Strong. The 7L5s are as near perfect for me as I've found. Warm but not overly. Great mids, strong bass but somewhat better on top than some other Heerlen Valvos.

Very good information about the tubes, good pictures as well. And very smooth purchasing process after that. Happy customer here. Five stars reward. Buy with confidence.

These 7LGs are wonderful valves. Great low end and mids. Somewhat revealing while just a tad warmer than the 7L5s. Love me some Valvo tubes! Thought they were history.

Don't know where y'all get them but I'm thrilled to have these 7L5s. Thought the Valvos were extinct by now. Sweet, sweet valves. Somewhat revealing with great low end and mids.

I replaced a pair of Genelex 12AU7 with a pair of Telefunken ECC82/12AU7 Berlin 1955 NOS+ for my Prima Luna EVO 300 preamp and completely altered the sonic and tonal characteristics of the sound stage. The later is now more opened, the low frequencies are tight and accurate, the mid-frequencies are breath-taking while the high-end is crisp and neutral. Both female and male vocals are front and center and present in my listening room. Chet Baker's flugelhorn is nuanced and smooth as well as Herbert Laws' flute. I have not heard Tony Bennett and Bill Evans' 1975 album sound so detailed until now. The holographic stage is starting to emerge after a short 10 hours of use. And the Telefunkens are very quiet. The investment was well-worth it. As a music major in college, I know what I like. Thank you SoundLumia for finding these rare vacuum tubes. P.A.H.

Very happy about this products performance. It really has enhanced the sound quality of my hifi amplifier Cayin HA 3A) more than I thought it would. Service, packaging and delivery have all been great! The only unfortunate part was it incurred a custom charge into the UK.

After a few weeks of searching for the perfect pair of 12AX7 and 12AU7 tubes, I stubbled upon Soundlumia. Seeing that they stocked many sets of of NOS tubes, I put in a request for some additional pairing information. Frank was quick to respond and promptly setup a call to discuss all of my options. He presented me with several pairs and discussed the variances between them all. In the end I was able to purchase a few matched sets that met my preamp, amplifier and DAC needs. I couldn't be happier with the upgrades. I will definitely be back for the more! Thank you!
