LNPA 150 Monoblock Amplifiers

R.E. Designs LNPA 150 monoblock amps

Power:
75 watts rms into 8 ohms
150 watts rms into 4 ohms
220 watts rms into 2 ohms

Note: The power rating into 2 ohms is a worse case rating. Typically units will range from 240 to 260 watts rms into 2 ohms.

Distortion:
T.H.D. = 0.1%.
Note: The harmonic distortion is second order and not considered audible by any present study.
I.M. Distortion is typically below 0.003%.

Signal to Noise Ratio:
1 watt = - 95 db A weighted
For units equipped with Vishay Bulk Metal Foil Resistors:
1 watt = - 104db or better

Voltage Gain:
26db (Av =20)

Input Impedance:
39K ohms parallel 470pf

Frequency & Amplitude Response:
A) -.1db at 5Hz to -.2db at 20Khz into 8, 4, and 2 ohms from 1 watt to full power
B) -3db at 100 Khz at 1 watt, -3db at 80 Khz at full power
Note: Due to the flat frequency response, there is less than 3 degrees of phase shift at 20 Khz.

Polarity Inversion:
None

Input Sensitivity:
1.25Vrms

Weight:
38 lbs each amplifier

Dimensions:
19"wide x 19.25" deep x 5" high

Warranty:
5 Years limited and transferable. The LNPA 150 is warranted to be free of defects for a period of 5 years from the date of purchase.

"... here are these 80 watt monoblocks effortlessly cruising at well over 100dB SPL. And it doesn't sound partucularly loud, just full! Amazing!"

R.E. Designs LNPA 150 Monoblock Amplifier / internal view

Each LNPA 150 amplifier has 2 large independent toroidal transformers, 2 large 33,000 microfarad power supply capacitors, built-in R.F.I./E.M.I. filters, a very simple wiring path and is fully regulated front to back... and this is only for one channel!

You will be impressed with what you DON'T hear with these amplifiers. The "glare" that is often heard from solid state components just doesn't exist in these amplifiers. The LNPA 150 delivers the lowest amount of coloration to the music. It will not homogenize, nor add euphonic components, nor mask the information on your source. It will however tell you everything you wanted to know about your loudspeakers but were afraid to ask. If you are looking for power, accuracy and reliability, the LNPA 150 is the power amp you're looking for!

LNPA 150 Monoblock amplifiers...
because its already been said for us."

Recording Magazine cover/click for review of R.E. Designs  LNPA 150 monoblock amplifiers  

"My Sept. '94 article on amps said that all amps sound pretty much the same, except when you overdrive them, and that you might be wisest to buy the cheapest amp that has adequate power. My experience with the R.E. Designs' LNPA 150 has made me rethink that."

"I will tell you straight-out that these amps literally caught me by surprise. To be honest, I did not expect to hear the kind of power, musicality, and finesse that they delivered..."

"The LNPA-150s sounds nothing like the typical hyper-detailed audiophile transistor amp, and indeed is closest to the VAC 90 and the Wavelength Audio Cardinals in overall presentation. In other words, no transistor sound at all-- relaxed, unstressed, very fast and open, and a remarkable similarity to the top rank of pentode amps and the upper range of the triode amps... the transistor LNPA-150 and the triode SV811 sounded almost identical, despite radically different design philosophies."

Sensible Sound review of LNPA 150

  "... the R.E. Designs LNPA150s were among the nicest amplifiers I've ever had the pleasure of reviewing. The 150s not only walked the walk, they positively strutted! They were almost impossible for me to characterize sonically because of their high transparency... I can only describe the midrange as "complete". These amps had the uncanny ability to properly reproduce not only the fundamental tones of instruments and human voice, but also the overtones and harmonic structure that are often distorted or glossed over by many other amplifiers... music through the LNPA150s was more realistic, detailed and full of life."
