This Pure Class A power Amp has a smooth and non fatiguing tone that rarely exists in a solid state amp. Its non-aggressive and deeply involving music reproduction makes it hard to believe it is not a valve amplifier. From human voice to acoustic instruments to rock, this amp loves every note you feed it and plays them faithfully as its instructed.

 

It is refined, subtle, and still managers to drive the majority of speakers effortlessly. Accurate and pleasing music is produced, regardless of the the genre.

 

The Amp employs dual mono symmetrical design with each channel driven by 8 Toshiba power MOSFET transistors. It also has an integrated DC servo circuit for Speaker Protection. The Electrolytic capacitors in the signal path are audiophile grade capacitors by either ELNA Silmic or Nichicon Muse KZ. Each channel is powered by a separate 500va Transformer and the filtration capacitors are the highest grade RIFA PFH169 series. The Tank like solid chassis for this nearly 30kg beast houses quality audiophile grade components purposely designed to work well together.

 

Power Output: 60 watts into 8ohm. 120 watts into 4 ohm (Pure Class A)

Dimensions: 485 x 430 x 165 (W x D x H)

Weight: 28kg

 

Would prefer a Local Buyer with pickup and inspection. Will take offers.

Dual 500va transformer means high current on low inpendece speaker should drive at ease. Glwts, little off the topic, to whom may curious what does transformer lable says - Wuhan Shinkansen Electronic Manufactory, and the colour of wiring config

What brand is this?

 

Can you advise how old it is / how long you've owned it?

 

Cheers.

It's LITE, a diy kit manufactory based in Guangdong, China,, just some light research has found, the amplifier board (a80), transformer and chassis alone would cost around 4200rmb which is 840aud when new, in China. Hope my Chinese can help anyone who interest in this deal.

Hi,

 

Thanks for that information - very considerate of you.

 

Hopefully the owner can let me know how old it is etc.

 

Cheers,

Btw, they also sell the assembled unit, however this amp board is not a shelf config and therefore there is no ref price available for you, but at least we know this could be a factory assembled unit. Also, this brand seems copy some famous brand's circuit design, and make them to the Chinese market. Not saying this is good or bad, but certianly can consider it coukd be a bargian on bang for the buck. Anyway, good luck.

I am second owner. Im not sure of age but doesn't seem too old. I am using it in a HT system at moment to power the fronts in a 7.2 receiver. I am replacing everything with a single 11 channel Atmos receiver to power all my speakers.

 

As a comparison this replaced an Anthem Intetgrated 225, and the difference is this has a more holographic 3D presentation.

I don't think this is a Pass clone. They mention "Manhattan circuit" in their description and I can't see the link to Pass Labs there. As with many DIY class A designs it seems to be a MOSFET-based amplifier though. The revised iteration of this A80 is called an A88 and the schematic for that one is available online. I'd be interested to know how many watts it draws from the wall at idle to determine how much class A bias the designer decided to run in that chassis and what kind of temperature it idles at, as this is a matter for personal choice as well as technical considerations, to a degree. Do you have a link to any more information @360Cisitalia ? I'm keen to apply some google translating to the documentation and learn a little more about it. ?

So it uses 150watts at the wall at idle .

 

It is warmish on the sides when it starts sounding its best but definitely not hot.  From this I would say it wouldn't compete with a Pass Labs.

Has to draw more than 150 watts if it is 60 watts per channel class A.

My 25 watt per channel class A amp draws 160 watts ftom the mains.

      Amorphous Tape Heads and dual capstans Automatic Tape Calibration Automatic Tape Type Selection Automatic Record Level Setting Built in demagnetizer Real time and Linear tape timer Dolby B and C Dolby HX Pro Automatic NR Detection (Deck automatically detects and switches to the type of NR used on the tape ) Large format Fluorescent Display Full Logic Transport Controls and more.  
      Here’s a good place that gives a run down on these wonderful sounding machines :

      Was part of a collection and very gently used. Deck have been previously serviced and all belts have been replaced. All functions work when tested. The silver top has some dings on the cover. This is purely cosmetic. The deck has a full bodied sound and presentation that delivers energy when the music calls for it. Top of the line  sounding machine with a wonderful sound and plenty of convenience features.
