model S513i “pastoral”, current-mode control amplifier with remote.
model S514i “rhapsody”, dual monaural power amplifier. (eqv S505i)





●model S513i control amplifier with remote
- 3 line input (2 x current/0 ohm 1 x voltage/20kohm), 1 line output (current)
- LED indication (1/red, 2/green, 3/blue)
- dimension 202 x 202 x 45 mm
  • +10 dB current amplifier to drive power amplifier efficiently
  • 32 steps, electronic control attenuator (output current limiter)
-> binary 2^9 bit encoded current divider (similar to DAC) with micro-controller
AC100-120/220-240V linear power supply (built-in)
- no operation button except power switch

remote commander: rotary volume, line input select (cigarette box size)

●model S514i dual monaural power amplifier
- current-mode input x 1, impedance 0 ohm
maximum 25 watt
  • dimension 102 x 202 x 50 mm
  • no operation button except power switch
AC100-120/220-240V linear power supply (built-in)


sound impression :
very real, rich, full-bodied, smooth reproduction.
can enjoy musical tone
wide dynamic range, well balanced bass to treble, overtone-rich
correct phase, wide stereophonic
this sounds like a tube amp
these amps have less non-linear stages, the sound is open and no suppression.

Hi Victor,

thanks for sharing.

If I do need only one input would the S505i Fluegel deliver about the same sound quality?

Thanks

Matt

It is a newer design
It is a discrete amp design - no ic
The power amp and preamp are current mode design

S513i is a current mode preamp
S514i is current mode power amp
Only current mode pre-amp can work with current mode power amp
