  1. Wow - such a great idea to focus on perfecting the 6.5" woofer. The two-way rises again. Any thoughts on: - What about trying a sealed box configuration? - Could this go with a first order crossover to something a little softer - say like an Esotar? The freq response curve for the pure-fi looks remarkably free of of ringing - it might not squeal when asked to play some higher notes. Bryan
  2. Incredible - can you write one of these pieces for every classic rock album? This article is almost a manifesto for a good turntable setup. Digital makes it all too easy for every engineer to just throw more spices into the soup. Who knows - that 02 master may have sounded fantastic until someone thought that dialing up the compression would be a good idea... Analog (for recordings that were recorded in analog) seems like a great strategy for keeping people with bad taste away from good recordings.
  3. From a non-engineering standpoint, there just has to be something different about sound that is born from mechanical vibration (analog) versus sound that is born from electricity (digital)- with "born" meaning how it starts in your living room. Yes, the turntable is powered- but only to spin the record. Somehow, translating vibration into electricity via a magnet just sounds different- and often better- than recreating an electrical waveform from a digital signal. I (remember) hearing a more realistic increase in loudness and image size when I had vinyl- does that reflect the way a magnet responds to larger vibrations? Have always hoped someone would delve more into these questions than samples rates and bits.
  4. Happy Audirvana user here- thanks for great program. This may have been asked already. Would love a way to more quickly change DACs - rather than preferences/audio system/... Maybe have a DAC icon on the top right of the main screen. Would also be great for a couple of other commonly used settings that are toggled - EQ and up sampling. Thanks,
  5. There is a misconception that comparisons mean reporting on which product sounds "better." However, the truth lies much closer to different high quality audio products having different "takes" on the recording. No DAC can perfectly recreate the analog event in time, no amp can boost the signal without altering it to some extent, and no speaker can exactly produce the sound pressure levels of an actual performance. At some point we settle on which approach we like best over the widest range of our preference of recordings (and then obsess over what the full DCS stack or Walker turntable sound like). In this regard, I find qualitative comparisons with detailed descriptions of the qualitative differences the most important when reading reviews and ultimately narrowing down components to try out. My two cents Nice review - Audio Alchemy was a legendary preamp back in the day- seemed to always be dueling it out with the equally legendary CAT preamp but for a fraction of the price. Comforting to know that a DAC designer has serious chops in analog for that key part of the design.
  6. So you can still get coupling over the length of the wire even if the 5v line is disengaged on the receiving end?
  7. Is this going to drive the computer audiophile mad to further perfect the sound quality of CAPS v4 and beyond? Maybe there are some new lessons lurking inside that $16,000 case?
  8. Nice review. This product has lots of appeal due to great engineering and expertise from Ayre in both digital and analog. The most interesting comparison- to me- would be to a Wavelength Cosecant with the Sabre option. Same asynchronous USB code, I think the same USB isolation strategy…. many shared constants, with the major variable being transistor versus tube output (which I usually prefer). Also interested in comparison with the EMM just for the sake of curiosity - the Ayre has a top-notch USB interface, full isolation on the inputs, an advanced power supply and discrete analog output stage derived from years of experience, very good clocks, and a good DAC chip - how do you significantly improve on this?
  9. Following this thread with interest - would like to try a linear power supply but am also put off by their relatively high cost. From my very linear point of view (no pun intended) - the "noisy" switching power supply of the computer could theoretically harm the sound by injecting noise through the power leg of the USB, injecting noise back into the AC line - and then the other components - or both. (I'm just not ready to believe that the there's an effect on the bulk transfer of data within the computer itself). By this logic should addition of an isolation transformer at the AC side plus something like an iFi USB power generator be equivalent? The linear power supply would be a more elegant one step solution but maybe more expensive.
  10. Hello all, Sorry if this a repeat question - I have searched but cannot find a specific answer. After my son took possession of my Macbook Air I now need a new computer for my music system. Was thinking of a used 2012 used Macbook Pro 13. Was thinking about taking the plunge on one of those Samsung 840 1 TB internal SSDs. My music library is only about 400 GB in AIFF. With a SSD am I still better off with TWO drives - one for the OS and one for music - or just put it all on a large SSD? What about partitioning the drive for the OS and music? Thanks very much! Bryan (borrowing laptops - external 1 TB firewire drive - USB to Eximus DP-1 - Ars Sonum amp - Merlin VSM speakers)
  11. Are people using a conditioner for the computer / hard drive / other digital components for the purpose of keeping digital noise separated from the analog components (amp, preamp)? For this purpose I would guess the conditioner does not have to be "non-current limiting" but just be good at heavy duty filtering. Any ideas? Thanks very much, Bryan
  12. Got one about 4 weeks ago. Love it. Sold my Burson DAC and kept this. It's a much faster, hyper-detailed type of sound but it still has great flow and midrange tone. If anything I would want it to be just a TINY smidge richer, but the balance is really, really close to perfect for me. I'm going to try an aftermarket power cable and see if that helps. The headphone amp is really great- I love the filter option for rock. Have tried the up-sampling (X2 and X4) but prefer straight no-upsample mode. Bryan
  13. Did the SABRE designers actually claim something crazy like "jitter immunity?" This sounds like an advertising pitch from companies who use their chip. What's interesting is that these DACs employ quite different approaches to the computer input. But I would guess they employ very similar circuits for the S/PDIF input. What this "equivalency" shootout suggests to me is that differences in the approach to the computer input still have a significant impact on the sound, and that these differences can be negated when the input is "standardized." Excluded from the "shootout" is the impact of the most important part of the DAC- the output stage. Wonder what he would hear if he subbed in a DAC with a cost-no-object output stage (Wavelength, Aesthetix, etc...) I'm not just partial to tubes either- when Pass or DarTZeel make a DAC I'll be lining up to hear it.
  14. | For instance, I like tube sound a lot. I have tube amps for that reason. But I know they're not accurate, and they are super hot, Many modern production tube amps have THD
  15. The Medea looks fantastic. I'm sure their lower priced converters sound nice as well. Still, I don't quite get it with a company in which you have to cross into the $10,000 models to first get a discrete analog output stage...
