  1. The above ½ dozen or so comments give some credence to the utility and sound qualities of current drive amplifiers when matched to appropriate speakers. When my active speakers were upgraded to current drive the improvement was worth the cost.
  2. Yes. If the "speaker" converts the file to digital for processing then the resolution is limited to its internal ADC/DAC's. Try the 5s in the den.😀 Stereophile liked the Audioengines. "Monitors" might not be the best for a room system so I'd be looking wider.
  3. Powered speakers are just that--speakers with amplification (and possibly basic pre-amplification) built in. As kumakuma said, if it has RCA in then the RCA out from the DAC should in all likelihood work fine. Just be sure either the DAC or the speakers have some volume control. Speakers with room management (such as my SGR CX4F-2) may do that in the analog domain. Even if they have internal digital processing they will often do that from an analog signal input. If you like the Audioengines you have then I'd be looking at their options. My Audioengine 2 speakers have served my computer use beautifully.
  4. All specs should ideally be measured. Relying on a manufacturer's PR machine is not necessarily wise. IIRC: Take the efficiency of the speaker (generally xxdB/watt @ 1 metre). [eg. 88dB] Work out the power required at your listening position. Sound pressure attenuates as the SQUARE of the distance.) [Listen at 3 metres=9 watts for 88dB] Work out how loud you want the LOUDEST transients to be. [orchestra=115dB, so say 106 dB in your room] Each 3 dB over the attenuated level at your listening position requires a doubling of the power. Therefore: 106-88=18dB, 18÷3=6. THATS 6 DOUBLINGS of 9 watts--9-18-36-72-144-288-576. 576 watts needed or 288/channel (for 2 channel stereo).
  5. As above.😀 If an amp overheats WITHOUT BEING OVERDRIVEN then I'd be taking it to a good tech for a checkup.
  6. Ha! Funny, I never connected the two "current"s in the wrong way. The different meanings totally overwhelmed the similarity (identicality?) of the words for me.
  7. I wonder how long it will take for "current drive" to become the norm. My 4 channel actives were considerably improved by the current drive option.
  8. I haven't listened to Linn speakers since the Kaber (designed by an Australian, Dr Rod Crawford) but they were excellent and I bought a pair. Rod recommended tri-wiring for noticeable improvements (I tried it and agreed) and substantial improvements by tri-amping actively (which I couldn't afford at the time). Hence my speaker upgrade was to a 4 active channel per speaker (SGRs in current drive mode). I thought I was finished upgrading 🤣 until I auditioned several of my favourite LPs after ultrasonic cleaning. The cleaning improved the overall sound quality and musical enjoyment significantly. (Only 750 albums still to clean.🙄)
  9. OP-- IMO there is really no way to put percentages on *sound quality*. Sound differences are another matter--that's mostly about room and speakers. Quality however starts from the source, wherever that is for you. Once the quality is lost then nothing downstream can get it back. For instance I've just started cleaning my LPs (one source) with an ultrasonic cleaner and the improvement in *sound quality* is very significant; and not just from the reduction in audible pops and clicks. Another example--I sent my active speakers to the manufacturer to be upgraded to the current model, which retails about $30,000. While they were being done I listened through a very old amp and some bookshelf speakers (carefully chosen at the time but probably about $2000 total if they were made today) and the music was still very listenable even though the overall sound was very different. Same sources.
  10. I used to put seat cushions on the floor in front of each speaker where the sound reflected off the floor.
  11. I've never been able to discern a difference with a blanket over the screen, but then the screen is closer to the wall than the speakers and I suspect the bass just goes around. I did get tired of looking at my reflection in the shiny surface though, so now I put on a "fireplace" loop. It does seem to warm the room.😁 In the hot weather I put on an aquarium!
  12. I've heard that the "column browser" will go.☹️ I use it all the time to scroll through artists.
  13. Considering the number of rumours about Apple since the early '80s and the number that have eventuated I treat all rumours these days as click-bait.
  14. My speakers and chair are on an equilateral triangle as in the diagram. I cross my speakers axis about 2-3 feet in front of my ears. I tried this 'cause it's what Ken Ishiwata recommends and I like it better than other angle arrangements. You will have to experiment to find what works for you in your room. AnotherSpin--No. Change the balance at the pre-amp. Sitting closer to one speaker changes R-L phase relationships as well as sound level.
  15. I don't know your answer but I've found Kingwa very helpful. I'd try asking him.
