As of April of 2015 this amplifier could be purchased with our UFO (Ultra Fidelity
Output) transformers. These took an already good thing and pushed the envelope a
bit harder with higher interleaves and more precision in the winding to achieve flat
response out to over 80 kHz. UFO transformers are now standard in this amplifier.

LOUDSPEAKERS / EARSPEAKERS

The SE34I.5 is designed to have it’s maximum power into 8 ohm speakers. That does
not rule out all 4 or 6 ohm speakers, or 12, and 16 ohm speakers. It simply means that
statistically it will work best with around 8 ohms. Since the only thing that happens
when you get a lot higher or lower than 8 ohms is the power output goes down, having
efficient speakers may make this completely a non-issue. You can not hurt the
amplifier by hooking up speakers that are more or less than 8 ohms. This includes
planar magnetic ear-speakers (headphones) which are too hard to drive with
conventional headphone amplifiers but may be as high as 30 or even 70 ohms. Most
of the time these work just fine and sound great with this amp.

We find that some speakers rated as low as 90dB 1w/1m get loud enough on this amp
to fill an average size room with a nice full sound. However, statistically 94dB or higher
is ideal.
!
UFO transformer, if configured with, will feature a chassis mounted switch on each
channel to change between hi and low impedance speakers, such as 4 and 8 ohm.
Switching can be done “on the fly” while listening to music to determine which way
sounds better.
