SET for 88 dB 4 ohm loadspeaker

The KR Kronzilla DX monoblock has 2 T-1610 Kronzilla tubes in parallel for a total output of 100Watt SET. Here is a review: http://www.enjoythemusic.com/superioraudio/equipment/0506/kr_audio_dx_monoblock.htm
The Kronzilla SX and SXI stereo versions output 50W each.

I own the NAT Audio Symmetrical preamp and the SE2se power amps. These are one of the most incredible sounding products I have heard in my life. Well worth the money.

Any amp that is designed to deliver the current neccesary for your personal level of musical enjoyment...ie Manley Neo 250 (EL34) or 500 (KT88) in ultralinear (SET) mode and others come to mind ...

Usa:

I have the NAT Symmetrical preamp as well. It has unbelievable transparency and very musical.

What cables are you using with it?

I think Audiofeil meant parallel single ended for the NAT amp; it uses 2 211 tubes in parallel but it is not push pull, else it could not be a SET.
