LampizatOr Horizon - Tube Rolling Paradise

I am breaking in the 802 as well and have found them to be a refinement as well, especially in the bass. I think the upgrade is commensurate to the change from OS1 to rs1003
 
Laszlo has kindly sent me demos of both ef802 and the subminitures to evaluate. I’ll post my findings on both here and the Baltic thread. The tubes they will be replacing in the 6sn7 position are Valvo e83f in xuling adapters. For greater context, the rectifier is a Tungsram pv4200 from Viennese factory and the output tubes (not directly relevant to H dacs) are Tungsram nickel e80cc. The latter have a neutral and linear high resolution character, so people can correlate them stylistically with their own output tubes.

Laszlo’s package arrived yesterday and I must say they look lovely! The ef802 are unused, so I immediately slapped them in for a week of burn in before any critical listening. The subminiature microphone tubes alongside look tiny yet exquisite. Based on what Laszlo tells me, they should be an interesting listening proposition and are great value. Since the tubes have flying leads, they are soldered directly into the base and avoid having another base / socket interface to navigate. Given our experiences of how different adapters can impact sound quality, this augers well.

The small “microphone” tubes look interesting- what type of tubes are they?

You are in for a real treat Mark. For me having tried them all including the much lauded and heretofore my very favorite TFKN c3gs, this TFKN ef802 is end game. ...not too hot, not too cold but "just right"
