| Gustard R26 - good but not the one Great comments. I am narrowing my DAC choice from my current Atom+ to the Qutest, Mojo, or Bifrost. I am not sure id there is that much difference in what I am most sensitive to, (female vocal and false horn edginess) in any of the Delta Sig... | |
| Speaker and Cable Suggestions Please YES, speaker impedance varies with frequency. The "nominal impedance" is a pretty useless value. Minimum impedance is more helpful, but that does not even really explain everything as phase issues can cause even bigger current draws around crosso... | |
| Speaker and Cable Suggestions Please Spend your money on the speakers as they are 99% or more of the sound. Use 14 or 12 gauge zip cord for cables. Yes, cables can make a tiny tiny difference and if you are a trained listener and have 30 year old perfect hearing, they can be audibl... | |
| Home network Fibre optic vs Ethernet Jeffery, I guess you have not dealt with fiber yourself. I have. Do you have a cleave anvil? Polishing machine? Inspection microscope? Curing oven? Have you looked into the specs for bend radius? OK, LC connectors are cheaper than ST and mas... | |
| Home network Fibre optic vs Ethernet So don't zip-tie your phono cable right on top of your ethernet 😀 OK, run your Ethernet down the opposite side of a wall cavity from your power lines. Just good dress. If I had unlimited budget and was building a house, I would be running all... | |
| Home network Fibre optic vs Ethernet Fiber is fragile, does not like bends, requires skill and equipment to terminate and test, and is expensive. We used it in large data centers for Gig-E and higher. Also handy in very noisy, and I mean VERY noisy environments. We use it for secu... | |
| Loudspeaker sensitivity and dynamics: are the two inexorably linked? Lots if issues identified. Some relevant, some grasping at straws to explain what we hear. We hear it, so there must be an explanation. I don't believe in magic, but I do hear things I don't know how to measure. We pay all that money for fancy ... | |
| Loudspeaker sensitivity and dynamics: are the two inexorably linked? Thermal compression happens to all drivers, high sensitivity or low. How much depends on how well the motor can dissipate heat. For example, fero-fluid may dissipate heat better and have lower thermal compression ( re increasing with temp) but i... | |
| Radical toe in once more Below the frequency defined by the baffle width, no difference at all as the sound is omni-directional to start with. Above that, it is all about the directivity of the tweeter. Every room is different, every listener has their preference. Corre... | |
| Loudspeaker sensitivity and dynamics: are the two inexorably linked? All drivers have a bit of a built in "dynamic compression" due to the suspension. So a high efficiency of the same sd, may in fact be more dynamic as it is in a lower excursion so not suspension "compressed". This may not be noticeable at all (sho... | |
| What is the science behind audiophile fuses? We call that "Madison Ave. Engineering" | |
| Really Long XLR Made my own from Mogami cable. You can always go to BlueJean if you are not DIY. Those runs were about 70 feet. Cables were not the limiting factor. ( and any recording you have probably went through hundreds of feet of the same cable already) | |
| Toslink The best modern USB, in asynchronous mode, is currently the best consumer link. TOSLINK the worst. It was not always that way so a lot of valid old biases exist. Can you hear it? Only your ears can tell. In a defective system with bad grounding... | |
| What is the science behind audiophile fuses? There is actually a reliability difference in fuse TYPES. ATO fuses are more reliable than 3AB or 3AG. Yes, in my days doing failure analysis, I found termination issues in 3AG fuses. There is a tiny tiny inductance with some cartridge fuses. Son... | |
| Midrange Increasingly Harsh Handy to have a decent small SS amp around. :) If Speakers, If I remember the Totems used the XT-25 tweeter that is anything but harsh. So I will have to be on the tube guessing camp. Note the range you may be hearing may actually be woofer bre... |
