M2Tech Joplin A/D Converter 384/32 - $2499.  - NOT A DAC! 6 preset E.Q. curves user selectable.

the JOPLIN is an A to D converter that is capable of turning any analog source into a digital file. It can digitize to any sample and bit rate from 44.1 kHz 16 bit to 384 kHz 32 bit. The inquiries came from all sorts of people with many different applications. Straight from Pisa, Italy and attached below are four applications, with flow diagrams, showing how the JOPLIN can be used for:

1. A digital grabber from any analog source - radio, television etc.
2. A digital archiver for vinyl collections!
3. A digital input to a DAC from an analog source in real time
4. A digital bridge between a digital source and a computer with no digital inputs.


 
M2Tech Joplin   
 
Reviews: Enjoy the Music Review By Tom Lyle

"M2Tech's first suggestion for using the Joplin is as an analog input for digital systems. I spent less time using it for this purpose than using it to archive digital, but during the Joplin's review period did use it in that way. I had in house two different DAC/preamplifiers, the Wadia 121 Decoding Computer, and M2Tech's Vaughan DAC/digital preamplifier. Both have similar purposes, but the Vaughan was the superior of the two, if only considering the fact that it is able to decode higher sample rates. It is also nearly eight times as expensive. Using the Vaughan, the Joplin performed as its literature stated it would. Utilizing the M2Tech Joplin as a Phono preamp to connect it to a Vaughan DAC/digital preamp was an interesting experience. As I said, the Joplin performed as advertised; I was able to use my analog front-end in the system when using the Vaughan DAC as a digital preamplifier. During this period I was comparing two different LP reissues of Antal Dorati conducting Prokofiev's Love For Three Oranges and Scythian Suite originally released on Mercury, the Classic Records pressing, and the newer double-LP 45rpm version from ORG. It was easy to differentiate the two; the Classic Records reissue was the far better at every quality that made this "Living Presence" such a joy in the first place, and perhaps one of the best sounding LPs in my collection. Most noticeable was that the ORG didn't have nearly the quality or amount of bass response as the Classic Records version, nor didn't have the soundstage, sparkling treble, or luscious string sound. No, the ORG version isn't a piece of junk, so if one missed purchasing the Classic Records version (or doesn't have an original Mercury pressing in perfect condition in the collection) the ORG will do just fine, as it is a great performance of two great pieces of music, the Love For Three Oranges being the better of the two, in my opinion.

The LP converted to digital through the Joplin also sounded excellent, but let's put things into perspective here. When I would archive an album at a decent sampling rate, say 96kHz/24-bit, then play the resulting signal through my system with an analog (tube, no less) preamplifier the signal sounded marvelous, highlighting the excellent way the Joplin had with converting the signal to digital with far less "damage" then I, or anyone else I suspect, would anticipate. When playing LPs directly through the Joplin, then through the digital preamp, the LP sounded good, but very good digital.

The M2Tech Joplin is a fantastic product. Not only is it a fantastic analog-to-digital converter, it also seems as if it was designed for a modern audiophile, particularly one that enjoys archiving vinyl. With its Phono equalization performed in the digital domain, the "straight wire with gain" paradigm comes closer to reality when one is transferring their precious records to digital formats. As a bonus, since digital preamps are becoming more popular every day, the vinyl aficionado is being invited to the party because of components such as the Joplin, which not only allows one to connect the turntable to a digital preamp, but to do so in style".
DETAILS
High-speed asynchronous USB connection. Single-ended stereo input on RCA. S/PDIF, AES/EBU and Toslink digital outputs. Auxiliary S/PDIF input for bridging. Selectable input gain 0dB to 65dB. Wide choice of equalization curves in digital domain. Various filter options (anti-rumble, anti-hiss, MPX). Remote control. Encased in a stylish aluminum case.

FEATURES
Joplin is a high performance A/D converter capable of handing up to 384kHz sampling rates and 32 bits resolution (USB output). It features a high speed asynchronous USB input based on the M2Tech hiFace Two technology, further developed to allow for higher sampling rates. A comprehensive output set (S/PDIF on RCA, AES/EBU on XLR and optical on Toslink) provide great connection versatility. Also, an auxiliary S/PDIF digital input on RCA allows for re-using the digital connection used for the Joplin for a digital source, as well as for redirecting the output from a digital source to a computer which is not provided with an S/PDIF input. Despite its price, Joplin encompasses a leading edge technology for data handling and processing. An FPGA is used to provide a seamless connection between the ADC IC and the USB port (both operating in master mode for low jitter reasons), as well as for a large number of important clock and data routing tasks, not to mention the VU-meter drive.

The analog stage is based on the best PGA (Programmable Gain Amplifier) available on the market, and allows for gain as high as 65dB (equivalent to 0.95mVrms for 0dBFS). A comprehensive set of equalization curves can be selected, to accommodate all Phono formats ever used from 1925 to the present day, plus eq curves for reel-to-reel tapes with straight output from the playback head.
The small size and stylish look of the Joplin allow for a noninvasive placement in every living space.

M2Tech - hiFACE DAC

Reviews:

Suono Review - by SUJESH PAVITHRAN on 03/2014

IN CONCERT:
There are two aspects of the HiFace to be explore one, as a headphone amp, and two, a standalone USB DAC. I’ve yet to build references for my computer audio gear and so borrowed a HRT Music Streamer II+ for comparison in the latter context. My headphones, an AKG K44, were plugged into the computer’s direct audio output and then to the HiFace for an easier AB comparison.

The difference when using the headphones was significant the HiFace was more detailed and balanced, my Toshiba laptop’s output sounding brighter and thinner in comparison. The HiFace had limited volume headroom, though, being fussier about headphone matching. My AKGs are entry level, but the HiFace still made its sonic benefits obvious it sounded richer in textures and better fleshed out in its sound staging.

 HiFace possessed something more organic and visceral in its overall presentation.  The orange unit sounded more lush, with better air over the treble frequencies, although I can’t say there was much to choose between both in the bass and mids. If you like a richer texture and warmer instrumental timbres in these areas, the HiFace is the pick.

APPLAUSE:
As direct competitors in the context of form, the acclaimed AudioQuest Dragonfly units are cheaper but the HiFace is more future proof. It overcame whatever reservations I had about entering the computer audio arena, turning me into a covert within a few hours. So yeah, it’s fabulous sonically.

How does it sound?

"Well, to these ears, the answer is 'fabulous': the little orange stick delivers a sound with a presence, power and dynamic freedom I've only encountered with some very expensive digital hardware, and has the bass grunt and control needed to make any rhythm-section-driven music truly exciting.

The day started well with Bob Marley in 24-bit/192kHz, took a turn for the more sombre mid-morning courtesy of the new 24-bit/48kHz B&W Society of Sound offering of Berlioz's Grande Messe des Morts

 

hiFace DAC

Hi-End Async 2.0 Audio Class USB 384/32 DAC

DETAILS

Highest quality stereo analog audio up to 384kHz/32bit available on your PC, Mac, Linux computer, iPad or Android tablet.
2.0Vrms line output level, 112dB THD+N.
Very low jitter oscillators, asynchronous 2.0 Audio Class USB.
Also drives most medium- or high-impedance headphones.
Highest value-for-money.

Compact size (2x1.4x8.8cm) with hi-end performance hiFace DAC has been conceived to make hi-end equipment performance at hand to budget-conscious audiophiles, without any compromise. One hiFace DAC and a laptop, Mac Mini or even an iPad make for a hi-end music file source at the cost of a middle range digital interconnect.


The hiFace DAC includes all necessary features to be the perfect DAC for all kind of hi-fi systems: asynchronous data transfer mode on USB 2.0, compliance with USB 2.0 Audio Class (no drivers needed for MacOS, IOS, Linux and Android), very low phase noise oscillators and last-generation conversion IC capable of 384kHz and 23 bits.


Windows users will enjoy it in Direct Sound, Kernel Streaming, WASAPI and ASIO (depending on the OS version), while Mac users will be able to take advantage from Integer mode and Direct mode.


While the hiFace DAC output is purposely designed to give its best with amplifiers’ and preamplifiers’ line level inputs, it may also be used to drive medium- and high-impedance headphones: try it with iPhone’s in-ear headphones.

FEATURES


1) LOW JITTER, LOW PHASE NOISE, HIGH STABILITY OSCILLATORS

Most audio interfaces and USB-provided DACs refer the data stream clock to the same USB interface clock, that often suffers a very heavy jitter (short range oscillator frequency variations). Thanks to two quartz precision oscillators used on M2Tech hiFace DAC, clock source for internal interface to the conversion IC features a very low jitter. Low jitter produces a very limited sound image distortion and degradation. Phase noise (main responsible for jitter) is also very low: this guarantees a short and long range clock stability, also reinforced by a board supply voltage regulation (e.g. at environmental temperature stability is 2-5ppm approximately, compared to 50-100ppm performed by oscillators normally used on commercial CD players).


2) USB 2.0 AUDIO COMPLIANCE

No need for custom driver. Using the hiFace DAC is very easy. Just connect it to your Mac, iPad or Linux computer and it will be immediately visible in the devices list and ready to use. A driver is still necessary for Windows computers, which enables for DS, KS, WASAPI and ASIO mode.


3) COMPACT SIZE, EASE OF USE AND VERY HIGH PERFORMANCE

M2Tech hiFace DAC features a very compact size and can be directly (or using an accessory USB A-A adapter, not supplied with hiFace) connected to a High Speed USB 2.0 port of any computer or tablet. A 3.5mm stereo jack socket provides an output stereo line-level signal, ready to be connected to a Hi-End system. No external power supply is required, as hiFace DAC draws its power from USB bus itself and regulates it with its internal regulators. hiFace DAC connected to a last generation mini PC provided with a High Speed USB port makes for a complete digital music source at very low prices (in the range of few hundreds Euros). Such system allows for listening any density and resolution music files (up to 384/32!), playing own CD's using a CD ROM drive, obtaining access to more than 10,000 web radio, many of which broadcast their transmissions with CD quality.
