  1. If I took a selfie with this lens the number would be 115.
  2. I'm really bored today. I need to get out more often. Uninteresting fact: The combined age of the lens I just used and the subject matter is 90 years.
  3. That looks like a piece of art glass. Very cool.
  4. 200 for the DAC. 50 for the RPI and case. As far as MQA goes, the only way I can tell difference is when the blue light comes on.
  5. I've been fooling around lately with different streaming options and I think I've settled on this. RPi 3B+ with a Khadas Tone2 Pro DAC/Amp. Balanced outputs, hardware MQA decode, selectable filters, lots of stuff for not a lot of money. This is my first USB DAC, my other two streamers are Toslink into Schiits. I was a little concerned about noise from a switching power supply for the RPi getting into the Tone2 but I'm using an old Apple iPad charger for a supply and it sounds fine to me. There is an option for using a separate linear supply but I don't think it's needed. These things just came out a few months ago so I hope I don't pay a price for being an early adopter. So far so good. It sounds very very good and I think it looks pretty cool too.
  6. Canon EOS M, Canon FD 35mm f3.5 (from 1975), framed in PS.
  7. I got a new DAC that seems too hot for my integrated amp. I'd like to extend the range of my amps volume control to a more normal level. Anyone here have experience using inline RCA pads for this purpose? I don't know the amps input sensitivity but I know its 32k ohms impedance and the DACs output is rated at 2v. Wondering what -db rating I should get, the ones I was looking at come in 3,6 or 12.
  8. My two other systems I am very satisfied with and don't play around with them much at all. My third system is my sandbox, I've been trying out all kinds of different Amplifier and DAC combos all with an emphasis on affordability. Just having fun. My only other experience with MQA is with headphones and I'm not one who enjoys headphones all that much, so the goal here is to hear how it sounds with good speakers. Initial impression is that MQA sounds excellent. Is it better? Maybe. Maybe not. The technology is interesting in how it supposedly gets more from less. Perhaps it's more VooDoo than science but sonically it appears to do no harm at least. Now the whole licensing and marketing debate I'm not going there. I just figure it's part of my Tidal service so why not give it a sincere try.
  9. I'm just as curious as you. Only way to find out is to actually try it.
  10. A few of you may be aware of my attempts to put together an inexpensive solution for streaming MQA. I tried the Dragonfly initially and failed. Volumio software running on the Raspberry Pi does not do the first unfold as it is called. The Dragonfly needs this first "unfold" to render full MQA. Using Volumio you need a DAC that does the full MQA rendering process via hardware. Up until now hardware MQA DACs were all somewhat pricey, enter the Khadas Tone2 Pro DAC headphone amp for under 200 dollars. This is a very nice sounding DAC and voila it works well with Volumio. So now it is possible to stream Tidal MQA with a dedicated streaming device for about 275 dollars.
  11. While we're on the subject of mqa dacs I posted in another thread about making a cheap streamer using a Raspberry Pi and a Dragonfly and how I failed in my attempt because the Dragonfly is not a full hardware mqa "decoder" just a "renderer". Well I'm going to try once more this time using the new Khadas Tone2 Pro Dac and headphone amp that just came out recently. It's 200 dollars and does full hardware decoding of mqa. It should arrive on Sunday from Amazon and we shall see how it goes.
  12. I'm running Volumio on the Pi. I was misinformed or perhaps I misunderstood that Volumio would fully render MQA using a Dragonfly DAC. Apparently Volumio will only work with a full MQA decoder DAC, the Dragonfly is only a "renderer", it needs a file that is already partially "unfolded" and then it will do the second unfold. In that sense my little project failed but it still is a great sounding streamer. (MQA is not essential to me and is a whole other debate that I'm not getting into.) It also allowed me to get away from using a DNLA server that was causing some problems with my local files. Now all three of my systems are using Volumio based Rpi streamers. I'm using the red dragonfly rather than the black which sounds noticeably better. Still a success for me.
  13. For me it's always an exercise in economics.
  14. Basic ingredients for an under 200 dollar MQA capable streamer. I'll cook it up a little later and see if it's tasty. I suspect it will be.
  15. More Weird Science vs. Weird Art. Musical Paradise MP-301MK1 prototype. With CCA & Taishan DAC (not a bad combo actually).
  16. That is a mini-toslink going into a fiiO Taishan dac.( arguably not a good dac but sounds better than the CCA alone.)

    What I Got Today!

    I waited two months for this and it was worth the wait. Sounds really really good with a pair of old Heresies.
  18. Why does that look exactly like another one being offered on eBay, right down to the table covering? If you do put it on eBay make sure you use your own pics or that would be misrepresentation bordering on fraud and probably piss-off the other seller too. Be careful, you could lose your eBay account.
  19. Thanks. I will check it out.
  20. Anyone have any experience with these class a amps? There are a few different versions of this circuit design available for short money on Alibaba. I am intrigued.
  21. You might consider the Schiit Mani. It's in your price range and get's very good reviews.
  22. I worked as a draftsman for 33 years at Western Electric/Lucent. Prepared thousands of BOM's. Specs and price was all that mattered.
