What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

Project Purpose:

The main purpose of this project is to start-up my company, Orchard Audio LLC, and to launch its first product - CRISPIN.

CRISPIN is a high performance stereo audio amplifier, which features low-feedback, low-impedance true-balanced output, high bandwidth and most importantly, sound quality. The result is a better-sounding amplifier at a fraction of the cost of its competitors.

To realize CRISPIN’s highest potential, Orchard Audio partnered with Digital Amplifier Company (www.CherryAmp.com) to utilize their Maraschino Module using Cherry Amplifier Technology®. As the first company to bring the Maraschino technology to the market, CRISPIN further sets itself apart from the crowd as a future-proof, forward-thinking and sonically optimized contender.

In a world of module based amplifiers, the Maraschino Module using Cherry Amplifier Technology® sets CRISPIN apart as a future-proof, forward-thinking, sonically optimized contender. Other module based amplifiers on the market use tremendous amounts of negative feedback to correct for output error. The result is ringing and high-frequency hash much like the mega-feedback Class-AB amps of the 1980s. CRISPIN offers amazing bench measurements without massive feedback or phase compensation networks. The Maraschino difference is simply better sonics. The harshness associated with other Class-D amps has been eliminated.

Digital Amplifier Company is extremely selective of their partners and their amplification technology is well respected and known in the industry. With this product you can get access to Cherry Amplifier Technology® at a reduced cost.

Reviews

The Audio Beatnik had the following to say after previewing CRISPIN: "There is a top-to-bottom balance that makes the amp addicting." and "Well, this unit must have been implemented very well; it had a very open, clear, transparent, and alive sound." See the full article here.

CRISPIN Can be Used With:

  • High end audio systems (feed with balanced or single ended sources from a DAC or Pre-Amp)
  • Computer audio / high end gaming machines - the most amazing PC sound system 
  • High resolution audio players like PONO and Fiio
  • Others...

Who Needs these Products? 

  • Anyone with an appreciation for music 
  • Those working in the music industry 
  • Consumers who do not want to sacrifice quality for cost 
  • Audiophiles

Project Funding:   

The funds from this project will be used to make the first production units of CRISPIN, as well as to purchase some lab and testing equipment to continue growing the business and come out with more cool products.

Risks and challenges

Prototypes have already been built and tested.

The risks are relatively low and mainly associated with lining up manufacturing for the production units. I have a few companies lined up to manufacture the PCB's and am in the process of getting final quotes. I will personally assemble the first batch of units to guarantee quality.

Another risk is lead time of certain components which can delay manufacturing. This is something that has been looked at and mitigated as much as possible.
