I listened to the samples letting them loop several times, both directly from my computer (via a pretty good set of headphones), and then on my main system (Mac computer > external drive > Cosecant USB DAC > pre amp > power amps > horns)... I drew th...

Hm, some very mysterious things are going on today similar to the observance of the Bethlehem star… :-)
I was commenting before that Lavry 924 is very slightly brighter then I feel a neutral peace of equipment should be. Once again it is not HF disg...

Well, I finally found and implemented a digital front end that I can live with. I have been so cynical about digital up to now that I have kept and used an old, cheap Sony player (albeit one actually made in Japan...) because up to now it seeme...

[quote user="joaco"]Hello all , i know this topic is almost about pp experience but since im experimenting with electricity i like to share some thoughts here . I builded a dac using very high quality components . As you know the power supply is crit...

There was a big room in there with big Schweikert speakers (with thier grainy and insultingly confident Sound), some king of not particularly good electronics and the entire EMM Labs’ front-end. Many rooms at the show used EMM Labs so-call preamplifi...

[quote user="cv"] I bet Yamamura is using non-causal filtering... this is all running off a music server, so could process everything offline. [/quote] Chris, there is no such a thing as “non-causal filtering”. Filtering is filtering, would it d...

I will address the low voltage DAC power supply first since it has multiple applications.The front end comprises a commercial 48/12 volt 20 watt dc/dc converter. This basically is used to provide 1000 volt isolation input to output otherwise you...

[quote user="Romy the Cat"]Computer playback has no autobiographical value. CD, LP, tape etc have autobiographical value and sometime huge value. A location on HD has none of it.[/quote] Agreed.[quote user="Romy the Cat"]... there are zillion valuabl...

[quote user="Mark Donahue"]Mani, Yes, the files were created using the HDCD Model 1 AD converter and you will actually get improved audio if your DA converter properly decodes the HDCD (Even at 88.2 kHz /24 bit!) There is information about the filter...

An FM broadcast of church bells from the major cathedrals around Sweden welcomed 2014. Blessed with holidays in my family's home in Dalarna, the miracle of a truly great room was granted. Built with logs in 1947, spruce floor, ceiling, and since th...

Guys,The purpose of the exercise is to get the best possible results from my existing collection of Red Book CDs - I have them, so I may as well use them, purchased en masse as they were during the rather overstated "demise" of vinyl - whilst providi...

Yes Romy, this is exactly my finding. Take an a to d transfer, vinyl rip, if you will, and listen to it on the computer via usb to dac. Then, take the same, preferably wav file, transfer it to disc and listen on cd transport. My experience is fil...

we replaced the AMR DP-777 DAC with New CEC DA 3.0 DAC (30k$) to test between three digital cables because we could not believe digital cables could have huge difference .The connection between CEC TL 1 and CEC DA 3.0 could be 4 Link (clock data ... ...

[quote user="xandcg"]Amir,If you are looking for a transparent DAC and it could have a built-in preamp, you may want to take a look on:Merging + NadacNadac Player, same but a built-in music server (or something).I did not listened to them, but at lea...

I admit I have too much fun lately with DACs. Whatever it is, my beloved 16bit DAC is back from the John Wright’s face lift. It is a third time when John does this specific Bidat. Interestingly that even John admits that for whatever reasons this uni...

Phil Gold wrote in his EMM review the following:
http://www.enjoythemusic.com/superioraudio/
The key consideration for any external DAC is how to minimize or eliminate jitter. We've seen analog Phase Locked Loops (PLLs), dig...

[quote user="hagtech"] I didn't want to steal any of your ideas. [/quote] This is very bogus notion. If the 6E5P is somebody’s idea then would be not me but Dima’s as he discovered the tube “for Sound aplicatios” in 90s while he was fixing a TV. Howe...

This is very interesting, Anthony. I do think that absolute polarity has own role to play. Also, do check the DC that might be sent out of your preamps, certainly with Placette and with your 10Y before the transformer. Chas it with disconnected Milq ...

Both ABB 20KVA UPS and Pure Power 3000 are IGBT transformerless UPS and the AC output of them is not perfect Sinusoidal .like Pure Power the ABB is also sensitive to AC quality.ABB 20KVA UPS does not isolate Neutral line but the Pure power 3000 isola...

Haralanov, I was looking at the subject of Brain Inertia from a slightly different perspective; perhaps I did not clearly express my perspective. The fact of the Brain Inertia is not under question neither from practical nor philosophical points of v...

[quote user="noviygera"]I have been thinking about how nice it would be to have have a good sounding DSP for crossover and delay functionality. I know this subject was covered here before but what was talked about is this DSP is not that good, and th...

Dear Romy,I have one of these machines. It is located between my digital source machines and a Lavry DA-924 dac. It is a machine designed for use by the mastering industry. I use it at home as part of my sound system. The reas...

Yes, the enclosure something like this, thanks for tip, miab, but it opens a door for desire more. A good box with fanless operation, 1920 x 1200 pixels touch-screen, 6 hard-drives, remoter control, $650 price tag is very good beginning. W...

I also like the convenience of playback via computer with ripped files. Theoretically, at least, and in my experience, if the cd is ripped properly, the sound quality is better than a cd player. The reason I think so is that no cd pl...

Yes the Bidat does lock 48khz very well and so does the Idat-m. Something even more suprising and coming from someone that knows these dacs very well is that on a few samples of Bidat they even lock at 96khz! Alas I am not so lucky. Mine is 44.1 and ...

[quote user="item"] The data ripped to the hard disk is - absolutely precisely - the same as the data on the CD. [/quote] Not necessarily. The data on CD is very much not the same as stream I uncompressed let say wave file. It was what I ment whe...
