    For what its worth it was 5, shocking. that's the recent reissue.

    This one is a lot better, but to emphasise these aren't vinyl rips at all.

    Great idea! I have one of their DACs and love it. Should have known they do an ADC as well...

    I ended up getting the MOTU M2 and am very happy with it so far. It comes with a standard USB A to USB C cable so you should be fine if you have an old school USB port. I think I remember seeing the M4 had better test results than the M2.

    I'm ordering the ADC next week, I just cant get the DAC+DSP set up properly for full uncompressed audio, as per BrilliantBobs comment, but I'm sure that wont be an issue with an analogue input.

    I think its pretty much the same. I use to run mark of the unicorn long ago and it was really good. I just left that somewhere. The only reason why I ordered the M4 is I play guitar and keyboard so I can also plug in and I'm planning to get a reel to reel so I need more track. I had a long talk with the guy at motu. He said if your intention is high fidelity 2 channel, youre better off with the M2. Same processor, same software.
    Which software are you using.. the performer?

    I'm just using it for analog transfers so Wavelab Elements 10. I guess I should check out the software that comes with it though.

    You know times I see a guy on the internet playing a full album in analog format. I put it on my old software and do a little editing. Bingo! When I run to my nakamichi or sony 3 head recorder,, the sound is a time machine.. Just like a new Robert Stigwood pressing in the golden years of HiFi.. Stayin' Alive baby.... :biglaugh:

    I'm also gonna get a set of what you have too for inboard. I wanna get another computer just for that and I'll set it up next to the other system. I record pretty fast. On my sparetime, the only thing I do is compiling music as much as I can. When I retire, atleast I just wanna listen to high fidelity. I'll still record but not as aggressive as today.

    I use a Creative Sound blaster X-FI HD, or I record to DAT then use a S/PDIF to usb converter.

    I had a sound blaster back in the 90's AWE 64. That was really packed with all the studio softwares, banks, EMU expansion board. That was a dream card to use. Windows 98 or 200 wont take it. I was so upset. I made so much analog banks with that software. They don't make those options anymore...

    My reason for wanting to it is to compare different masterings really.

    My aural memory is shocking, either that or there is no difference!! Heresy!

    I appreciate much in todays technologies even when it comes to recordings. As far as I remember when I started doing this as a hobby all the way back in 1981, I was doing a cut and paste on the physical tape itself. So when I see something like what you have, That's a giant leap for me.. like a gift from god. Of course your gonna go to an obstacle in the beginning. but once you polish and get it running right, then record lock and load. This is where I'm gonna put the new computer with your sound card and connect the 2 analog output to the 3-head sony deck recorder. I'll also attach my mobile turntable. This recording station has a 6 deck cassette player below that can run 9 hours or pure digital or analog sound.
    I have a 9 inch (229 mm) LED VU meter coming in so I can monitor the recording and playback from a distance..

    When I do some vinyl dropping I use a handheld digital recorder from tape out, works really well.

    Did a quick price for a decent set up, sans RCA cables of course:

    [​IMG]

    $170 or thereabouts? I'm sure you could do it a lot cheaper on Amazon or the bay of evil.

    I still have a couple AWE 64 Gold cards. Still have joystick to MIDI adapters. Problem is, you'd have to build a PC with an ISA slot, slightly limiting your CPU options. 8MB of soundfont memory. I've still got the XP drivers in my "drivers" directory. Load the DOS TSRs into himem for adlib compatibility, good ol' days.

    I also have a modern SB X-Fi Titanium HD PCIe, and it still can run MIDI soundfonts just fine (Someone asking $2000 on Amazon right now...;) . Here, I just loaded up 1.7GB of soundfonts:

    i like those VU's, nice. My scruffy set up for now:

    Hopefully it will move into a better listening position soon(house move) and will tidy the cables up. I do a lot of headpone listening at the moment.

    Thanks...
    I was looking at your card. This is surprisingly nice. This one has other hifiberry has toslink in and out plus RCA. They didn't really say the analog dac chip. But I been using the burr brown op chipsets for a long time and theyre always good. exactly the same as yours.
    HiFiBerry DAC2 Pro
    .........Infact I have an analog preamp right now with a volume, bass, mid, treble control or bypass the tone that carries the "burr brown" op amp chipsets. I can interchange the chipsets on this preamp. The 2 of these below Ive used it on several occations. The original JRC (japan radio co.) where really good chipsets back in the early 80's. They sound very analog so as the ad797. The rest of them I haven't tried yet. Well theres only one way to find out.

    LME49710
    JRC5534
    - midrangey
    AD797 - excellent bass and excellent high
    OPA627BP
    MUSES03


    This is the datasheet of your new card. I think I'm gonna go for this.

    Datasheet DAC+ DSP
    Overview
    The HiFiBerry DAC+ DSP is a high-resolution digital-to-analog converter for the Raspberry Pi (newer models with 40 pin GPIO connector). In combines a Burr-Brown DAC used on the HiFiBerry DAC with digital input and output and also comes with a powerful digital signal processor.

    Facts
    • Stereo analog output (sample rates up to 192kHz/24bit)
    • Stereo digital input and output (input up to 96kHz, output up to 192kHz)
    • 300 MHz Digital Signal Processor (6144 instructions per sample incl. FFT and FIR accelerators)
    • Dedicated 192kHz/24bit high-quality Burr-Brown DAC
    • High quality asynchronous sample rate converter that can upsample/downsample/mix audio sources
    • Onboard EEPROM allows to board to boot and run even without the Raspberry Pi
    • Users can upload programs developed with Analog’s SigmaStudioStereo input and output
    • Connects directly to the Raspberry Pi, no additional cables needed
    • No soldering, comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi, it is conform to the Raspberry Pi hardware-attached-on-top (HAT) specification.
    • Compatible with all Raspberry Pi models with a 40-pin GPIO connector
    • Directly powered from the Raspberry Pi, no additional power supply
    • Gold plated RCA output connectors
    • Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi

    Note that the actual board might look a bit different. Layout and components might change without further notice. We do not guarantee a specific PCB layout or specific components.

    Connectors and Jumpers
    1 TOSLink input (up to 96kHz)
    2 TOSLink output (to 192kHz)
    3 Analogue output
    4 DSP Analogue inputs (P4)
    5 external DAC I2S output (eDac)
    6 DSP digital inputs and outputs
    DSP analogue inputs (P4)
    The analogue inputs connect directly to the DSP. These are NOT audio ADC. The inputs are designed to use external analogue control like voltage sources or variable resistors to control a DSP program. You need to design your own DSP program to use these. Pin 1 is the top-right pin

    GND 1 2 +3.3V analog power supply (up to 0.1A)
    AUX ADC 1 3 4 AUX ADC 0
    AUX ADC 3 5 6 AUX ADC 2
    eDAC I2S output
    This output provides the digital I2S data stream that is used for the onboard DAC. Note that there is no support from us to configure specific external DACs. This should be only used by people who can not only debug I2S, but also create their own DSP programs. Pin 1 is on the top left.

    +5V 1 2 GND
    Raspberry Pi SDA 3 4 Raspberry Pi SCL
    I2S BCLK 5 6 IS2 DATA
    I2S LRCLK 7 8 MCLK
    DSP digital inputs and outputs
    This output provides access to additional I2S inputs and outputs of the DSP. This should be only used by people who can not only debug I2S, but also create their own DSP programs.

    Wow,,, Blast from the past. I gotta admit those tone banks actually sounds really good. The softwares that came with it are pretty good. I have a keyboard controller and I was able to emulate the korg prophecy sound. Almost close to the PPG wave 2.2. The thing is just like what you said. Sometimes it locks dues to ram. Can you upgrade the ISA for more memory?

    On that 2nd setup, I don't need the analog input. I just want the analog output.

    Might be better using it with a OS like PiCorePlayer, I can't seem to get the digital input working properly on Raspian so far.
