    Smyth Research Realiser A16

    I contacted Smyth about getting the update and was told it has not been determined whether they will offer it. I haven't heard any more. I hope this is not the end of it. Like some others, I am concerned about future upgrades not being available for the old boards.

    Smyth Research Realiser A16

    Well it is good to know the A8 and R972 with Trinnov worked properly. It seems that although Trinnov Altitude prepros may do ADC on multichannel analog inputs, it is infact correct to do the SVS calibration without Trinnov, and then route Trinnov to the A8 (or A16) analog inputs, like you were...

    Smyth Research Realiser A16

    Is it possible to do measurements of an unequalized system with analog sweeps, and then for playback insert the equalization after the source but before the A16? By equalization I am broadly including frequency, time and delay compensation. If the equalization is done separately for each...

    Smyth Research Realiser A16

    @mlkri: You are misinterpreting my impressions. I don't know whether it is good enough for high-end stereo emulations, which is the scenario I was addressing. Some evidence suggests that it may require some manual fine-tuning and perhaps extremely neutral gear. Even then there would be...

    Smyth Research Realiser A16

    Looking at the documentation, it seems your speculation is correct. In fact, it seems likely that no sweeps are available over HDMI directly from the A16 (even 2 channel). In other words, the HDMI output is strictly for passthrough, and sweeps are only over analog, which is the same as the A8. I...

    Smyth Research Realiser A16

    I certainly hope that 7.1 sweep signals can be output over HDMI PCM, and one doesn't have to resort to a DVD player. What would be the configuration in the latter case? Is the DVD input to or bypasses the A16 (on way to AVR)? The prior would present the same problem, and the latter would seem to...

    Smyth Research Realiser A16

    I think the Realiser does attempt to improve the sound, in the sense that duplicating a finely-tuned room can improve the timbre as well as the soundstage relative to a standalone headphone. For example, the Realiser can (perhaps) remove the 6 kHz peak in the HD800 if of course it does not...

    Smyth Research Realiser A16

    I am new to Kickstarter and don't know how it typically works, but this proposal seems odd to me. For example, I don't see the point of raising 100K given an apparently much larger investment in R&D to date.  I guess I would be more inclined to partake in Kickstarter if it was a make or break...

    Smyth Research Realiser A16

    I second the interest in knowing whether the A16 can output test tones over digital, either optical or HDMI, for input to AVR with modern room equalization.

    Long awaited Smyth SVS Realiser NOW AVAILABLE FOR PURCHASE

      I am not sure what could be licensed, I am not familiar enough with the technology. I have worked on equalization of wireless channels, but that is of course different. Just pointing out that there is a large gap between an equation or algorithm and a working implementation.   A...

    Long awaited Smyth SVS Realiser NOW AVAILABLE FOR PURCHASE

    I wonder whether some are understating what Smyth has accomplished. There is a large gap between the theory and implementation here; it isn't the novelty of the prior that would be licensed. Also, not everyone wants a computer platform for a variety of reasons. I don't feel that Smyth was ever...

    Is a Sonic Impact T-amp a good match for Klipsch Cornwall speakers?

    Well, I would have to check on the difference. I was aware that they changed from a front ported design in original Chorus to a passive rear radiator in Chorus II, but unsure of other changes. To clarify, I dont find the combination of tube amp and Klipsch fatiguing. In fact, I enjoy it...

    Is a Sonic Impact T-amp a good match for Klipsch Cornwall speakers?

    I have Klipsh Chorus II with modified x-overs, and listen to them (mainly classical but also some jazz and pop) with both Charlize T-amp and Wright 2a3 monoblocks. With NOS driver (preferred choice is RCA vt-231), I prefer the monoblocks for what I consider a smoother and more realistic and also...

    which speakers do sound like Grado/Alessandro headphones?

    My Klipsch Chorus II speakers seem close to grado SR-325i sound to me : forward midrange, deep and impactful bass, and extended highs. The speakers are not quite as quick, but the soundstage is (of course) more realistic. I had the x-over network redone to remove some of the hardness in the...

    ATH-W5000 for all types of rock? (prog, industrial, etc) Plenty of info in post

    Iron_dreamer , for those who have not heard or are not as familiar with the SA-5000, can you give a view on how the ATH-W5000 differs from AKG K701? I find the speed of the AKG K701 slightly slow in upper bass lower mids for my taste, especially with symphonic brass I think the...

    ATH-W5000 vs. ? on veil and/or speed

    Can anyone characterize the veil and/or speed in the upper bass or lower mids of the ATH-W5000 versus other popular cans, in particular SR-325i, SA-5000, and AKG-K701? What I am after is the relative amount of low pass filtering as manifested by a fuzziness or widening of the attack in certain...

    headphone amp that also serves a good pre-amp?

    I have an mpx3 slam with preouts on order to use with wright sound 2a3 monoblocks and klipsch chorus 2 speakers (101 db). Like some of the other amps listed above (e.g. levinson) with 100K input impedance and relatively low sensitivity, I was actually concerned about having enough gain(!). I...
