Bricasti M1 DAC vs PS Audio Direct Stream DAC


I own a PS Audio Direct Stream DAC that I like a lot but heard my friends system with the Bricasti M1 and I am strongly thinking of changing my DAC and would love your feedback from other members that have heard either or both. I know they are both great but really thinking of changing my Dac from PS Audio Direct Stream to the Bricasti M1 DAC. I use a HP Desk top computer as source with Jplay and JRiver Media 19 and the outstanding Tellurium Q BLACK DIAMOND Reference USB Cable. The rest of my system is below. I listen to Classic Rock, jazz, vocal, some modern music and the usual audiophile stuff.

Thanks

For Bricasti M1 DAC owners only: If you connect your Bricasti M1 DAC to a pre-amplifier (any pre-amp), you need to turn the M1 volume control to ZERO since this allows the full signal to be sent to your pre-amplifier. If you reduce the volume on the M1, you cause more bit reduction meaning you lose sound quality. If you connect the M1 DAC to a power amplifier (this is what I am doing), you FIRST must measure your M1 volume settings. You measure the number where the sound is the loudest you listen to (mine was -15 to -20db) and the softest you listen to (mine was -35 to -40 depending on the recording). I discussed these settings with Bricasti and they said the goal is to have the M1 CLOSE to 0db front panel attenuation on the most dynamic recordings, this is mostly found in symphonic recordings and DSD ones.

You have two options. Option #1 is to move the internal PCB jumpers, they are right next to the XLR connectors, 3 pins so just move it over to the other 2 pins. This adjustment activates the two screws on the back of the M1 DAC for manual adjustments. If you WANT to change the level though, you will need a 1k-0dbfs tone and an AC voltmeter to read the voltage otherwise you cannot level match them. In most cases there is too much analog gain in systems and to get the M1 direct optimized this has to be adjusted, once done it really provides the BEST analog signal path and yields the most transparent sound with perfect level control with no side effects from added cables or resistor ladders in the level controls of the hi end preamp, all of which have an effect on the sound. This will get the digital attenuation at the minimum amount needed and the result is the best of both. Please be careful since some older M1 DAC's do NOT have internal jumpers (please call Bricasti to review).

The 2nd option (this is what I am doing) is to keep the M1 DAC the same (no changes) and adjust the power amplifier so that it accepts a higher incoming signal meaning you can move the M1 DAC volume control closer to zero. After conversations with Bricasti, Hypex and the James, the builder of my Hypex NC400 bridged mono amps, he is going to remove R141 from my Hypex NCore NC400 bridged mono blocks, thus lowering gain by 14 dB, requiring 14 dB higher M1 volume setting for same playback level. NC400's 14 dB allows 7 dB greater bit resolution than the M1's 7 dB. This is more complicated than I expected but everyone thinks it will work fine. As I understand it, you have to balance the M1 DAC to the power amplifier in order to achieve your M1 volume settings CLOSE to 0db. If it does not work, additional changes can still be made to the Hypec amplifier and/or the M1 DAC. In summary, for normal operation, the Bricatsi M1 DAC has a digital attenuator so minimizing the amount of attenuation is ideal, therefore setting analog gains is critical for best performance. I think I got everything. cheers, Howard
And some people think downloading/uploading a sd card for firmware updates on the DS is a hassle.....
I tried several usb cables. Chord silver plus, audioquest diamond and king rex y art & Upower powersupply. Chord is nice. Better than a standard usb cable. Audioquest is very good but in my system a bit to analytical/clinical. You get a lot of details but too much for me. The king rex is a usb cable that makes a match made in heaven for me. It has plenty detail but also a strong fundament and u believable depth and width. Yes, it is expansive but cheaper than the audioquest. Also lesser recordings sound much better. With the audioquest they sound shrill but just right with the king rex. I am very happy I tried these cables before buying. The king rex stays!

I wanted to get back to you on your question about the after market Linear Power Supply I bought for my Auralic Aries Extreme w/ duel femto clocks that I use to feed my Bricasti M1 DAC.

The SBooster BOTW P&P ECO Linear Power Supply with the Optional SBooster Ultra Filer is an Amazing ad to my Auralic Aries Extreme Transport. Man it took probably close to 400 hours or so for it to break in so that was a pain in the neck and I wasn't sure what was up for a while but it settled down and opened up finally and was well worth the wait. Highly Recommended...
Transport - Guys I keep hearing over and over how a good dedicated disc spinner transport is better than the Network based transports. Can anyone recommend a really good CD transport for my Bricasti that is not crazy money? Would love to know what you guys think and are using? Thanks
