New Phono ADC/Pre from MiniDSP

I'm intrigued. I like the ability to choose between RIAA, DECCA, and Columbia equalization curves, not that I would really use it, lol! I wonder if it is done in the digital domain, which I now think is best because of the potential for greater accuracy. The capacitance options are, umm, interesting: 50pF, 100pF, 500pF. It would have been nice to see something close to 0pF as many Audio-Technica cartridges could benefit from that depending on the cable capacitance. 150-200pF would have been very nice for some older cartridges like those from Shure. But of course equalization is the name of the game here.

Is this enough to beat the Parks Puffin? That magic declicking feature is still what makes a truly modern phono preamps for me. Of course this is selling itself as more than a phono preamp.

I can see myself finally selling my Manley and getting this if it measures well.
 
but there is a big difference... it is not a standalone phono with an analog output... ;-)
Yes, the lack of analog output, and as @USER mentions, the odd selections of loading options are curious. Not show stoppers, but a bit disappointing. Analog output would add cost, and for many would not be a show stopper, as most folks these days have a DAC. And I suppose you could EQ out the impact of less than the best loading? Don’t see myself replacing my Apt Holman, but if I didn’t have that, I’d certainly consider this and the Waxwing as options.

The Waxwing offers a little more. Here are my settings that differ from the default values that I made today for my audio-technica:

²⁴File: AT312EP
Differences to the default settings:
¹Volume: -6dB
²Gain: 63dB
⁸Hi: 30kHz
¹²Magic: On
¹⁴Derumble: On
¹⁶Charging: 200Ω
¹⁹Output: 24/96
²⁵ᵉFine tuning: -1.3dB


The miniDSP only has 4 presets. That would be too few for me. Only L/M/H are offered as analog gain settings and position H would be too low for my LOMCs. You would have to use the digital gain here, which can also be used for the intermediate values. The Waxwing, on the other hand, offers an analog gain in 1dB steps before the ADC.

Nevertheless, this is a good start for miniDSP and more of it please :cool:
 
It’s cheaper and less capable than the waxwing.

A few years ago I digitized a couple hundred LPs and de-clicked them in SoundForge. It was time consuming and tedious.

I’m hoping next to year to buy a Waxwing, finish the project for about 500 remaining records, donate them to a local thrift store that actually sells them, eBay the Waxwing, and be done with vinyl. Alternately, I’ll give it to my daughter, who is into retro tech.
 
Indeed the ADC stage measures extremely well. Not sure there is a standalone ADC that comes close to its performance without adding a ton of other features and cost.
 
Introducing ADept, a pocket size audiophile Analog to Digital Converter
The miniDSP ADept is a compact high-resolution A/D (analog-to-digital) convertor that accepts single-ended (RCA) or balanced (on XLR) audio signals. The digital output is available on SPDIF coaxial and TOSLINK optical connectors, and can also be recorded to a computer or mobile device via the USB-C connector. Adept combines low latency, high sample rate and extremely low noise floor performance to provide optimal digitization of your favorite analog audio content.

The miniDSP ADept is also a phono preamp (with a turntable connected to the RCA inputs) with accurate phono equalization for moving magnet or moving coil cartridges. In addition to the standard RIAA phono equalization curves, we've used the power of DSP to provide additional curves that will be of interest to the keen collector of older vinyl. A range of input gain, resistance and capacitance values are provided to optimize for any cartridge and can easily be saved and recalled in your favorite preset.

So why did we come up with ADept? Because we couldn't find a pocket size converter that has audiophile performance (117dB SINAD/123dB SNR), that can be controlled with an IR remote for a wide range of modes (phono/preamp) and doesn't break the bank. It truly is a multi-use box with applications from hifi/studio all the way to audio measurements.

ADept is now available for 299USD on our shopping cart, a very attractive price to rival current ADC offerings. Check out the product's datasheet and user manual for more details and feel free to contact our team if you have any questions!
 
Very interested in the ADept -but one question : My speakers are limited to 24/96 inputs -having read the manual -I think if I hook up my computer thru the ADept USB input and then tell the ADept to expect 24/96 input -can I then expect the digi outputs of the ADept to output a 24/96 signal to my speakers ? I think this is the case?

It's an ADC. Why would you run your audio through your computer's DAC into the ADept's ADC, back into your speakers' DAC? Makes no sense.

I'll add, this is essentially a $300 product intended to digitize vinyl records. If you're not doing that, its probably not for you.

So you can room correct the sound, it just like many do with their digital sources. Those who would use it like to play vinyl, but do not view the ADC>DAC path as an issue. It's a similar product to the Parks Audio Waxwing https://parksaudiollc.com/#next, which is fairly widely used by the vinyl folks around here. If I didn't have an Apt Holman Pre, I'd probably buy the Waxwing, but would also consider this product.

I do not see any reference to room correction in the ADept product description. Additionally, the user I was replying to specifically mentioned using a PC as the source. If you want room correction on a PC, you can buy Dirac Live and run it on said PC. This user was talking about sending a digital stream from said PC to this box only to send the same digital stream on to his active speakers.
 
Have read the instructions for the ADept . Personally -have no interest in running a PC into my stereo rig -but my speakers (Meridian DSP-5000 24/96) have a upper limit of accepting 24/96 digital information.). I actually own and use a number of ADC s and a couple of Parks Audio Puffins which output RIAA phono to digi outs. So back to my question -I THINK? per the instructions? that if I hook up a computer via USB into the ADept and send it 24/96 music data -that will set the ADept to output 24/96 via SPDIF to my speakers ? I can disconnect the USB connection and the ADept will stay set at 24/96 output. Am mainly interested in the ADept because of it's relatively high RIAA input overload specs. Would be nice to get one to Amir and see how it actually shakes out.

Do you see an advantage over the competition here?
 
Advantage ? Not sure? The standard for describing phono input overload is to list at what level in mV at 1 kHz you reach 1% distortion. The specs for the ADept give overload specs in mV with this description "maximum analog input before digital gain /RIAA EQ........". Excuse my ignorance -but anytime someone moves away from a "standard" spec it's either because they've got a better / more complete description or it's designed to befuddle and confuse ?

Sorry, I replied to the wrong comment. My point was towards the utility of the device. More specifically, that the ADC aspect allows the option of feeding the phono signal to whatever flavor of room correction you prefer, be it Dirac on a PC, Dirac Live on a DSP device, Trinnov, Room Perfect, ARC,….
 
A phono pre from MiniDSP? Is it still a fad? lol
I think it's a very useful product and quite unique. I feel it checks a lot of boxes like unbalanced RCA inputs for one, and it has both line AND phono inputs (so it's good for tapes etc. as well as a phono preamp). Not to mention it can handle either moving magnet OR moving coil input. YAY! To cap it off, it has a USB output so I can finally digitize (and preserve) some of my old vinyl from the 70's and 60's that were never released on CD or other digital formats on something other than a cassette tape. Laugh if you will, this thing is an important missing link type of product and I applaud it's arrival. Kudos to miniDSP!!! Now, let's see how it sounds... The good people at miniDSP have informed me that they have already sent one to Audio Science Review for testing so fingers crossed!!!
