Today there was a broadcast of Gaetano Donizetti “L'elisir d'amore” from our local Shubert Theater by Boston Lyric. I always love those small-stage production – they might not have the killing cast but they try honestly and have that boutique quality...

[quote user="steverino"]FM is Analog Signal Processing vs DSP. The compression aspect is only really intrusive on orchestral works. Pop and jazz are already compressed and chamber music presents a more limited dynamic range if not limited contrast. B...

ArmAlex the fun thing is that you read Romy posts here without understanding his ideas and copy paste Romy instructions in your Audio system and the result is lower than those audiogon guys (an example of your audio logic -> you buy gryphon spea...

The other night I listened to a Girl with Guitar master tape. A friend has a home recording studio that would make most comercial studios not only jelaous, but also broke. A highly modded ATR 102 in 1/4" half track and a vintage stereo microphone; ...

[quote user="Romy the Cat"] Still, I feel that air-cap has own coloration. This “no resolution”, vacuum-clean HF dynamic is coloration itself as I do recognize this characteristic across all music that the corrector plays. The sound of the air-correc...

[quote user="Romy the Cat"]1) Be very careful with use Halco resistors. They were very good 15 years back but they turned south very aggressively. I bought a party of Halco in 2005 and I forced myself to trashed them as they were very noisy. You...

[quote user="Romy the Cat"]Hm, I took the anti-RIAA signal converted and run CD player into the phonostage. The RIAA curve was fine and the effect of the HF volume and frequency-depended quantization did not expose itself. So, it looks like the p...

A Federated Mike started his new venture ultimist.com, the portal where he feel people would like to go to do “purchase research”. Those poor audio dealers do not get that someone might have interests in audio outside the brands, shopping and nee...

Hi,[quote user="Romy the Cat"]I heard 4 (!!!!) complete contradictory descriptions how high level of jitter manifest itself subjectively – interesting that they all derived from the engineers whose credibility is very high (not juts the audio-tweaker...

[quote user="peter foster"] The TU-X1 sounds to me as though there is a dolby processing happening even when the dolby feature is off. [/quote]You might check if your country decoding switch is not in a wrong setting. It located at the very top of th...

[quote user="drdna"] The first key would be
that the digital reproduction be of a high enough sample rate to fall
below the threshold of perception. The scond would be, in my mind, that
the process of reproduction not create a new structure, but r...

That is so much pisses me. A few days back I posited this like and was laughing that this guy record in DSD (which is in fact not DSD but SACD, I do not think he has access to DSD) in order to sell his recording in PCM 2X and 4X? Why do those people ...

Yep, Telstar. The 1547 was use in Sony and Teac CD players and believe the first CD-SACD machines used that chip. I know very little about those chips and have none of my personal experience to deal with all of it. The reasons why I brought it up bec...

Ok, it turned out that I had all caps and coils "in stock" necessary to adjust the filters very close to Romy's recommendations.Its still not perfect, and I had the mic 1m from the membrane of the driver (had not yet rea...

Whoever implemented and experimented with my slicing of lower MF range by 3 channels (Upperbass, Fundamentals, and MF) know how powerful it might be. Changing loading and volume of each of the channels it is possible to write any sound one might ...

[quote user="slowmotion"]Good news if the analogue stages of the DCX2496 is so bad. So the improvement of a modified unit should be worth the ekstra work, and remove some of the x-overs negative influence on the sound. Which is always good to know be...

TwoGoodEars posted at his blog a report about is listening session or some kind of installation. I still have no idea who’s installation it is: Jean Hiraga or Be Yamamura. Nevertheless, I think it very much worth to look into it.

[quote user="twogoodears"]Yes, maybe the 120 db/octave is THE trick for complex multi-ways systems of highest resolution, yet this barbaric:-) slope can ONLY be achieved by digital domain crossovering... unfortunately, as a satisfied user of TacT RCS...

I was thinking about it in past. I do not particularly believe too much in point source. We have no vertical resolution by our hearing and if drivers located strictly in a vertical line then in longitude domain they are single point source. Of course...

Guy, that is one excellent clip!
It does explain a lot of the problem, and I can understand why Pop and Rock are most affected, and why Jazz and Classical are more often less horribly affected.
It seems a lot of older but remastered recordings ...

I think the sorry state of the music industry (s/ware, sound) is primarily due to:a) the trend toward audioVISUAL and the ensuing market for productsb) how people listen to musicA) I believe this is self-explanatory; the bulk of the market invests in...

Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resonances as the reso...

Using the PP2000 has been a very interesting experience. Immediately listening I am NOT struck that it is the most wonderful improvement ever, which I have said before is a GOOD sign. Usually the seductive sound changes are colorations that are enj...

I am glad that you mention your use of 120A. I never heard it (consciously) and I bought it juts due to advice of 3 people, one of them was the guy who sold them. I have no idea what to expect from them but I think they shall not be too bad. I asked ...

I have heard hundreds and hundreds of audio systems and mine is by far the best. Honestly nothing even comes close. There is a scientific reason for this. MY system starts with a PERFECTLY tuned room...something overlooked by ma...

Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...

[quote user="cv"] But I don't think they are doing this here. What I would bet is that that they are running the thing in A2 with a much lower Z primary, using a lower B+ and high standing current. They are also using feedback which will help the ban...

Thanks for the link, el`Ol. The original Görlichs, when they still use aluminum layers were very interesting, thought they were soft suspended drivers that is not my cap of tea. BTW, for whatever it worth the Magico new version does not use ADT...
