Hey all … I know some of you have this unit… and I have yet to see any negative review on it… For those unaware - this is essentially a USB to I2S converter that seems to mate well with the DS. All reports give it a thumbs up… These reports have been in multiple threads - and I was hoping all cou…

Just to confirm matrix have confirmed external 5v psu is outside of spec and may not work. 7-9v is the spec.

I will be buying Keces p8 for the Matrix so i need to decide on which voltage to use. I am thinking of either 6v or 7v. May I have suggestions for it?

The lowest voltage specified should be best. I would go with 6v or 7v. 7v is more versatile…

Lower voltage is ‘better’ for the matrix as the voltage drop provides lower heat stress, however, sonically different voltages sound best depending on which psu you use. So, the answer is try each voltage your psu provides and decide which sounds best and if they sound similar go at the lower voltag…

Hmmm, I didn’t like 5V whether it was from USB, an iFI, or the Uptone LPS. Then again, I didn’t do serious testing. Just listened for a while and did a better/worse judgement. (Hey, don’t knock it… I still get my eye exam that way.) @rq1111 , you would be best to check the true voltage output of …

@RobH - as you know, I’ve run the Matrix @ 5.15V (external) w/ “data only” JMaxwell USB cable from N+; using Sbooster Ultra filter. I’ve since purchased a custom built Farad Super3 LPS (6V), making sure the Matrix operation meets warranty. Having much SQ success w/ Farad Super3 LPSs. Glad it is work…

@RobH - I posted my results giving feedback to the collective in another thread. The WW PS7 USB beat the JMaxwell & Curious “evolved” USB, both isolating the VCC w/ kapton tape (pics in the thread). However, not like it was OMG. But; it was better all around. Since this is a Matrix thread, here are …

After reading the suggestions, I think i might settle for 6V. Initially, I was thinking 9V as many says it sounds good but another group says 7v which is also good. Also there is 5v group says good. As my Matrix has not arrived and I have not order the P8 as I need to decide what voltage for the M…

@rq1111 - the voltage selected is all over the range (wrt SQ) if you search fully on this thread. If I bought a PS with selectable output voltages, I would try the Matrix at different voltage settings. I like to run it at 5.15V from my once Sbooster w/ Ultra and settled on 6V because of Matrix warra…

Thanks! Cardi. Hope i will get my Matrix this week.

What happened to the taped Curious cable?

I’ve been happy with the JMaxwell.
