What about a digital buffer: a device that takes any digital stream, from whatever cheap, village source you feed it, stores enough to reclock it properly, and then feeds it out to the DAC of your choice? Since even the cheapest reading devices offer...

[quote user="Romy the Cat"]I might be not “getting” what you are doing but it looks to
me that it is not near close to “CEC TL0X vs Berkeley Alpha”. The Berkeley
Alpha is just an interface to get stream of DAW but CEC TL0X is digital transport. We...

Yes, you are right it is rather my negative prejudges and I should not proud about it. It perfectly possible that Bend is a fine performer…. Still, it is a transformer and no mater what you do is a band-pass filter. It is still inductance at the bott...

I am pissed, disappointed depressed and my ego is a size of a brains or an average audio-Moron.
For a last number of days/weeks I was truing to do something extremely simple and still I had failed with a disasters fiasco. All that I need was some ki...

[quote user="Markus"]Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that.
I would love to use ho...

After learning about the Schwarz’s circuit Dima declared that it will be very simple to build into the unit a good quietly multiplex decoder as the plug in modules as a substitute to the original modules. This will change nothing in the Schwarz but t...

[quote user="anthony"]Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. [/quote] It was very interesting to read about all of it. If you have a socket for YO186 then you can accommodate all 4V tubes and I si...

You may remember I also use transformer shunting for attenuation, in my case the taps are selected by "communications" shunts/relays. My output is quite low R, but variable, and only the transformers for isolation (no "active buffer". I was wonderin...

Ive tried various configurations but was unable to produce a recording that is similar to the fm transmission, although its not too terrible. I monitor the sound by using the same output of the Sansui that goes into the DAW. Replaying the file, I n...

[quote user="rdrysdale"] We are using about an 18 foot path for the sub. What we need is for some smart electronics guy to design and build a processor just strictly for time correction, and nothing else, no EQ, or crossover built in. [/quote]

Some Hypex-type sub amps with ULF X/Os have high level inputs. Maybe this is a way to feed the thing from your DSET, if this is a goal for you? I think most of this type X/O and amp combination have an input buffer, and most of them have 180/variab...

I've been following your project with some interest. I've been experimenting with a horn loaded mid bass cabinet and have isolated a resonance around the same 220hz mark you mention. I feel/felt the inadequate cabinet bracing is my problem but you me...

Two reasons that audiophile designers always harp on the analog end of the CD player: they don't have the wherewithal to develop a new ADC algorithm and they believe the word "analog" sells boxes. I thought there were already digital audio devices th...

perfectly able to understand you play a different ballpark but what if a good DAC is not such a thing.
I orderd a Vicol shigaclone to be build in the Behringer Ultra Curve, with a spdif tube buffer to a Behringer Ultra match for upsamplingand a tub...

Well, the pros always say, all balanced, and ground everything, and this is the usual short cut to quiet, long cable runs in complex systems. I think Guy H will make something for you if you can explain to him what you want. Again, while one buffer ...

Well, Romy, it took me a while but I finally got the cobwebs cleared out of the phono stage, and the Shostakovich 10th was totally engaging as music (via the TAP). The recording is the (late 60s) Melodiya (stereo) with Yevgeny Svetlanov/USSR Syp...
|
|
Hi Romy, IMO, the reason for you to get that feeling is that from the beginning they were made to read data and not audio, thus some jitter was (and is) not considered an issue, as soon as it can be corrected.The internal CD drive audio o...

I came across this classical streaming station while searching out the net for new music enlightenment. I believe it is in an experimental stage and the only one of it's kind. It makes available 16 bit 48khz signal streamed. It does need a high bandw...

Hi,[quote user="Romy the Cat"]All that I need was some kind of vacuum tube buffer that would have no-gain of a very low gain and that would be sonically completely transparent.[/quote]Completely transparent is very hard to do. Try the following:6AS7 ...

As with everything audio, one has to put it in context in order to evaluate it. In my case, the ML2s have a reasonably "high" and stable input impedance, the TAP TVC has a reasonably low (and totally stable) output impdance, and my cable runs are sh...
|
|
Well, there's noise, attenuation and impedance to reckon with, at a minimum.The TAP TVC I use claims that the step circuitry itself is "out of the signal path". OK, fine; but so what? Doesn't the voltage have to "cross" something, somewhere, at som...

I did not use or know anyone who uses anything by Borbely but Placette basically is the same idea – a discrete op-amp. It has also a proprietary switchable voltage divider and assembling is “made for transparency”. If not Placette then I still would ...
|

Yes, my DSET is fundamentally the same as yours with 6 channels, three fullrange, 1627a for Channel C. The largest difference is probably that my DHT channel has its own B+.My preamp is quite different though, being a hybrid based on 10y. It has a ...

I have already got a tape recorder and now here is what I am thinking. Since there are quite a few tapes with Dolby A, Dolby B, Dolby c, Dolby S, Dolby SR, DBX and since some of the tapes were not properly EQ I would need an abili...

Ah, the current source!! Serge, you must be right. Ironically I did hear about this method of extracting cartridge signal by Dynavector when I used tier 507 arms but I forgot about it. If am not mistaken the Dynavector is not a phonostage by just vol...

Hi!English's not my mother language so I'd have advices to choose wich Melquiade could be the best for me...I read that there's a lot of different versions...and I wasn't able to email Romy because of the robot barrier.I've very good 95db Fullrange B...

Hi Paul,My understanding is that the placette has a unity gain buffer. At full CD ouput levels of 2Vrms into an S2 - it wouldn't quite get that into the S2s 16 ohms - but say it did, you'd be looking at about 109db from a pair...I'm not saying it wou...
