I am comparing they two streamers upstairs in the main system as following: Pi 3B with HifiBerry Digi+ Jameco 1A 5V linear PS via DH Labs optical to ARC DAC8 I could have used the coax out on the RPi and an RCA to BNC connector, but the above arranement allowed for only swapping the Ethernet cable. I'll cut to the chase - the RPI is a phenomenally good bargain and doesn't miss that much as compared with the more expensive uRendu setup. And, it could be that I'm hearing mostly power supply differences. Perhaps I'll need to reconfigure the HDPlex for 5V operation as another variable. What I'm hearing for the most part is more dynamic impact and emotion with the uRendu. I'm listening to the opening tracks from the soundtrack to Fanstastic Beasts and Where to Find Them. There's great bass drum slam with a very realistic sense of its air wafting through the hall. Fine percussion is ever so slightly better delineated with the uRendu along with a greater sense of sustain from the harmonics with upper percussion like the triangle. It seems I'm always a bit late to the party, but I can positively say that now I get it about this cute little box. FWIW, I did take Soundchekk's suggestion and configured the buffers for 20k and 600k which means it's pretty much playing from memory as opposed to streaming. Wifey's out of town this weekend, so I'm gonna do lots of comparative listening. I want to compare voice, piano and complex synth content to get a full measure of other character differences. Stay tuned! |

You're not comparing RPI vs. MicroRendu!!! You've got a complete shuffled environment of interfaces, devices, cables . SW asf. For sure this will lead you to wrong conclusions!! For sure It won't be a RPI vs. MicroRendu comparison here. However. Obviously what matters is the outcome. If you're happy with what u hear already, I'm pretty sure with some minor adjustments you'd be even happier. BTW. Did u try PiCorePlayer? With all mods on (HDMI off - LED off asf)? Are u streaming PCM or flac? There's plenty of stuff to gain. BTW. Here's my HifiBerry thread (my first HAT project): There a numerous tweaks listed. Many of them will also apply to the HB digital interface: http://www.diyaudio.com/forums/digital-line-level/285811-hifiberry-dac-pro-hw-mods-anybody.html And. If you've got 45years of diy-audio experience I really don't understand why you run after stuff like HDPlex supplies. That stuff is something for folks like Mercman who can hardly turn a screwdriver. Enjoy. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

"...I'm comparing how folks actually use them..." It is just you. Sorry. You're comparing two systems, your unique systems. Not just two devices. The thread title is misleading, thus your thread and conclusion is pretty useless to us folks. If you intend to run a rather useful comparison "Pi vs. MicroRendu" hook your Audiophilio up to the Pi and microRendu. That at least would make a little sense to us folks. You'd still don't know what software tweaks are implemented on the MicroRendu. One thing for sure. Svensson was closely following my SB Touch adventures and trying these himself. I'm pretty sure he put quite a focus into that area too. Then the USB ports of the PI are not known for audiophile qualities. Bottom line. If I'd run a to me useful shootout on USB transports, I'd put at least something like a $100 iPurifier to the test environment. That still would make a nice combo and a bargain solution in comparison to the MR.

"Many folks have asked to provide my impressions for comparing the two" Yep. "the two". Not the six to ten.

Thx. I hope he'll get it now.
Nope. The MicroRendu comes with a well done USB port.
However. If somebody is looking for a nice SPDIF solution I guess he might have a valid story about a system - his system - and not a device.

A Pi alone won't make a great transport. It requires a little effort to make it sing. But it's IMO possible. Most people are just lazy and rather put a grand or more on the table for the next potentially greatest thing ever - because somebody said so. ----------------------------------------------------------------- blog latest >> The Audio Streaming Series - tuning kit pCP |

I agree with you on all accounts |

I think.... At least it should matter. But then it might not.

"Does it matter soncially?" If you'd ask Archimago: No way. All measurements look the same. It's all in our heads. From my perspective: Everything matters! How much it matters is a different question and a very personal matter.

Yep. It was. I honestly care about you. I keep trying to get you away from that commercial brain-wash/marketing track. You recall how much fun you had when attaching a stupid coil to a cable? Can you imagine how much fun it is to build your own system!?!? Just try. And you'll never look back!

quote the text you find "ujustifiable"? I don't have to foggiest clue as to what you refer. Do you? Or is this yet another fabrication of what I've actually posted as you did with this post? Actual posted comment: "After extended listening" Fmak's delusion: "After extensive testing" |

attempting to *support* even more delusionary claims. Do you really not get it? Honestly, I never expected a rational answer because - there clearly is none. Any more than I expect you to acknowledge your fabricated *quotes* from me. All one has to do is read your claim and the linked post and then wonder why it is you have such difficulty dealing with reality. Do you actually have conversations with human beings? You know, someone asks a question and you respond. At least to that which they've said and not with an imaginative perspective of reality? You've never answered any number of questions I've asked you. Do you not understand the words? Thanks for verifying your inability to substantiate English language skills here on Planet Earth. :) |

Okay maybe I exaggerated a little in favor of the RPi. |

After reading all this, I've determined I like the rpi3 Because of the Lego case option. |
