From our JJ KT88 vacuum tube listening test:
"The JJ KT88 power tube has the best imaging of all the tubes in this category. The bass is unique in that it compresses the very bottom end. This provides incredible bass response without ever losing control. Overall a great KT88 tube for orchestral, opera, and jazz music."

Solid Performance

by

There's nothing bad to say about these tubes. They have an organic punchy tone in my bass amp. Not edgy at all.

Follow Up Review

by

I can only give these tubes a ten because the scale does not allow for more. If it did I would rate them much higher.

The description of these tubes is accurate! Vocals are liquid and palpably present. Excellent detail and very transparent but never harsh. Dynamic and engaging.

The sound stage is excellent however the perspective is of being in one of front 3 rows, centre position.

If the associated components are up to the task these will produce very good results. If the results are not as described look elsewhere in your system for deficiencies.

Surprisingly Good KT88 Tube

by

Just replaced KT120's in my Cary Rocket 88R. As good as the KT120's were I wanted greater coherence through out the frequency range and a fuller (not warmer) presentation.

The tubes have been running for 3.5 hours. So these are my initial impressions and will follow up once they are fully burned in.

Initially, considering the price or for that matter any price, I'm shocked at how good these tubes are in my system. The KT120's are definitely not a bad tube but the JJ's are in a different bracket altogether, perhaps it's system synergy, whatever it is I'm glad I gave the JJ's a try.

Very pleasant sound

by

I'm using JJ KT88s in a Musical Paradise MP-301 mkIII amp (6.5 watts per channel), playing into vintage Sansui SP-2000 speakers. The sound is superb - smooth and holographic with a gorgeous midrange. The initial brightness cleared up once burned in, as expected. I chose these tubes based on the Tube Store's recommendation about imaging and I would definitely buy these again.

Great KT88 Tube

by

I have two pairs of made in Czechoslovakia TESLA KT88's and recently got a chance to look inside one as it died. The occasion also afforded me the chance to compare it with a JJ, something I've been wanting to do, so I sacrificed a JJ KT88 and broke it open. I was not terribly surprised to learn the JJ tube was made as well, if not slightly better than the late 90's TESLA. The welds and the general finishing was better with the JJ. These are VERY well made tubes. I've never had an issue with failures, red-plating, rattle or any other of the common problems of cheap tubes, with these. Highly recommended!
