Last Nov. 11-16 2025, at the Rockville Hilton Hotel was held the Capital Audiofest.

During this event Gershman room using Lampizator EUFORIA with application of KR 5U4G was awarded Best Sound of the Show by www.enjoythemusic.com/

Comment from Rick Becker : The DAC was LampizatOr’s new flagship tube DAC, the Aphrodite ($105k), fitted with 5U4G tubes from KR Audio in the Czech Republic. I’m partial to tube gear in general and Lampizator, more specifically, as I use their Amber 4 DAC, which has now been replaced with the Amber 5 model. The Aphrodite was placed upon a VPI turntable platform set on the top shelf of a Pangea equipment rack ($249). The bronze sheen seen on the front and side is an artifact of the light falling on the textured finish. The chassis is black, like the perimeter of the top in this photo.

From Mark Conese, Easton, Connecticut :

The Quad KR KT88 replaced Ray Reserve (selected Chinese) KT88s that were in the amp. They are employed as driver tubes, transformer coupled to the 300b output tubes in this amplifier.
Being used as driver tubes, they are not run very hard. So they should last a long time in this amp.
Compared to the Ray Reserve KT88's, the KR KT88's have much better low level detail retrieval leading to an increase in soundstage size. They are also extremely quiet and provide more punch in the low register as well as provide increased dynamics.
Overall they sound closer to the input signal. A definite upgrade. I'm verry happy with them so far!
Also the KR 5U4g's have been performing flawlessly and sound great.
