  1. Sorry Brian Bazinga is the KECES still avaialable?
  2. New large affordable LIFEPO4 battery packs. Any new thoughts on this avenue? https://www.amazon.com/s?k=LiFePO4+portable+power+station&rh=p_89%3ABEAUDENS&s=price-asc-rank&dc&qid=1592689743&rnid=2528832011&ref=sr_nr_p_89_1
  3. Im currently looking at these. They have LIFEPO4 batteries which as I understand it maintain voltage better and have better impedance specs. Please dont quote me on that. The Sine wave only works for the 110 outlet as I understand it. If you are powering 5-12 volt range it doesnt apply. Based on the specs the smaller unit will power my NUC for 5 hours. My Etherregen and DSpeaker 8033 much longer. Wish some of the members with more electrical savvy backgrounds would take an interest. https://www.amazon.com/s?k=LiFePO4+portable+power+station&rh=p_89%3ABEAUDENS&s=price-asc-rank&dc&qid=1592689743&rnid=2528832011&ref=sr_nr_p_89_1
  4. Hello Brian Is the Keces power supply still available?
  5. I just bought an intel NUC to run Roon core. I added a 256 GB M.2 Transcend SSD for the OS drive. The computer came with a 32 GB Optane drive that I had to remove to add the SSD. I own a very small amount of music and was looking to perhaps put the music on a thumb drive. Something with super fast read speeds like the Corsair Flash Voyager GTX 128GB USB 3.1 Premium Flash Drive. https://www.amazon.com/Corsair-Flash-Voyager-128GB-Premium/dp/B079NVJPKV/ref=sr_1_5?dchild=1&keywords=fastest+usb+2+flash+drive&qid=1592064906&s=electronics&sr=1-5 Then I ran across these USB 3.1 Gen 2 to M.2 NGFF SATA SSD Enclosure Adapter, External SATA Based M.2 Solid State Hard Drive Enclosure Reader for M.2 and thought perhaps I could use the Optane card for music storage in one of these storage cases. The info says these are compatible with intel optane memory. I really dont know what this can is used for aside from cache. https://www.amazon.com/NVMe-PCIe-Gen2-Enclosure-PCI/dp/B07MLJ7FRD/ref=sr_1_19?dchild=1&keywords=optane%2Bmemory%2Bto%2Busb%2Badapter&qid=1592090580&s=electronics&sr=1-19&th=1 Why not as I already own it. Can Optane memory be used in this manner? Any thoughts on which option would give better sound quality. Neither is a particularly expensive solution but I'm curious if one would stand excel for sound quality. Or is there a better sounding solution like using the micro SD reader. Thanks in advanced to anyone who want to chime in.

  7. I would recommend Spatial Audio speakers as well. I own pair of M3 Triode Masters and the width, depth and height of the soundstage is beguiling to say the least. However they do perform best when placed away from your front wall. 24"-30" is what I believe is recommended. No shortage of great reviews out there. Also check out the Spatial Audio section on Audio Circle.
  8. Just upgraded my system and have some items for sale for anyone who wants to get started in the wonderful world of streaming digital audio. Buy one buy all. Please feel free to make offer. All offers considered. Pictures available upon request. All items guaranteed to work properly. Please feel free to ask any questions. Uptone Audio Ultracap LPS 1.2 with stock cables (New $435) Used $375 Sonore Microrendu 1.3 with stock power supply and cables - $250 2X - TPLink Fiber Optic Media Converter MC220L - (New $23 each) $25 for the pair Fiber Optic Cable - 6 Meter Multimode Duplex (62.5/125) - LC to LC - Orange (New $15) Used - $7 Uptone Audio USB Regen Amber with stock cables and power supply (New $175) Used $75 Linear Power Supply (2 rail adjustable 5 - 12 volt) This is a 2 rail version of the well reviewed "El Cheapo", R-Core transformer linear power supply. Both outputs are user adjustable via a small screw inside the unit. For buyers uncomfortable setting themselves or who do not own a volt meter I would be happy to set and label for you. I used this unit to good effect to power the units above in various configurations. Happy to provide pictures of the inside. I believe this was branded as Zerozone on Ebay when purchased. Used - $50
  9. I found a page that mentions non-optimum attenuation as well as the idea that some cables have the attenuation built in. 1. Fixed Attenuators: Fixed optical attenuators used in fiber optic systems may use a variety of principles for their functioning. Preferred attenuators use either doped fibers, or misaligned splices, or total power since both of these are reliable and inexpensive. Inline style attenuators are incorporated into patch cables. The alternative build out style attenuator is a small male-female adapter that can be added onto other cables. Non-preferred attenuators often use gap loss or reflective principles. Such devices can be sensitive to modal distribution, wavelength, contamination, vibration, temperature, damage due to power bursts, may cause back reflections, may cause signal dispersion etc.
  10. This idea of attenuation of the fiber signal has lead me to do some research. I remember reading somewhere that there might be a minimum fiber optic cable length requirement in order to limit back reflections and I wanted to confirm this. Have not found any info to support this yet however I did see a guide that says you should put all attenuation on the receiving end only. https://community.fs.com/blog/guideline-for-fixed-fiber-optic-attenuator.html There is also quiet a bit of info on how the attenuation is done and what this does to signal loss and signal distortion. Perhaps a new thread needs to be started to compile this info. As we all know this equipment is designed for very long runs and we are using it for very short runs. We need to compile some numbers for the common transceivers and receivers we as a community are using including their output and input specs to determine how much attenuation we really need in a given run to be at an optimum operating point.
  11. Jud I have the monoprice CAT8. I dissected one last night and the shields are indeed connected at both ends. The procedure was quiet simple. Razor blade off the plastic sleeve. Cut the shield wire to the metal housing. I then removed the metal housing because I wasnt confident I could keep the wires from touching the housing. This was done with a pair of needle nose starting at the seam in the metal housing. Bend it away at both ends and it pops right off. This did indeed leave a bit of a loose connector. However these cable are inexpensive enough that I was not too concerned. This weekend I will hot glue the ends to avoid stressing the solder points. Its not pretty but if you want to experiment its pretty straight forward. Common sense tells me to connect the unconnected shield end upstream.
  12. Wow Alex that was a fast response an most assuredly inline with the great customer service Uptone has gotten a reputation for. As I understand it the recommended install would be Switch > longer RJ45 (no metal ends) EtherREGEN > Short RJ45 (Best quality sanity will permit, metal ends OK) > Renderer Does the community have additional comments from the field?
  13. With all the positive reviews pouring in for the Etherregen I have taken the plunge and have placed my order. With the ER I am looking to finally update my network / digital front end and am looking for some advice from users on the best upgrade path. I currently own a first gen Microrendu fed by a pair of TPLink optical modules. I also own two LPS 1.2 Supercap power supplies. I have read and reread the forums along with the comments from Uptone and Sonore regarding their products regarding best implementation practices and I am trying to decide on upgrading to the Ultra or the Optical Rendu. Does the addition of the Etherregen appear to negate the need for optical isolation making the added cost of the Opticalrendu a worthwhile improvement in sound quality. I understand that this is very subjective but I would love to hear peoples opinions of the two front end chains. Can anyone speak to the MOAT created by the ER negating the need for the optical isolation? Aside from the addition on the optical module to the OR are the OR and the UR otherwise equal? Switch > RJ45 > EtherRegen (LPS 1.2) > RJ45 > Ultrarendu (LPS 1.2) > DAC Switch > RJ45 > EtherRegen (LPS 1.2) > optical cable > Opticalrendu (SGC LPS)
  14. Id be curious to see how it stacks up against the MiniDSP SHD studio. A bit more expensive at $899 but you get Dirac built in and the Studios is all digital and takes an outboard (ie: upgradeable) power supply. Frankly I am quite surprised this Volumio streamer isn't getting way more traction in the forums here. I mean come on we all have great DACS here on this website.
