NORMA Audio Electronics http://www.tmhaudio.com/Norma.htmThis amp is outstanding and a real bargain. (bought for 3500,00 in England as a demo unit) I never heard the voices from Al Jarreau, Jamie Cullum, Bobby McFerrin in such a way. Really amazing! The bass is exceptional. See the review from HiFi+ on that homepage, and I can confirm the writing. The amp needs a very good stand/support (SRA). (The preamp section of the Integrated is omitted and the NOS1 has a connection to the power amp section only via internal jumpers) Joachim |

Low frequencies this is an exerpt from http://barefacedbass.com/technical-information/Huge-lows.htm-Quote- 20Hz - 40Hz = rumble These are the kind of lows that are felt more than heard and add a certain rumble and sense of scale to movie soundtracks, pipe organ music and some electronic music. The sub 30Hz realm is very much sound effects territory - explosions, thunder, et al. There is very little content in music below 30Hz so club systems tend to cut off at this point if not a bit higher, whilst live music systems as seen at major festivals / stadiums tend to cut off at 35Hz (which makes the systems a bit more efficient so you need less gear to reach a given SPL than with a system with a 30Hz cut-off). A low tuned bass guitar does have output below 40Hz but it takes a seriously potent speaker system to reproduce that at high SPL. Sub 40Hz output adds a certain size and weight to music. It is almost more felt than heard and is rarely perceived independently of higher bass output (because any low frequencies will have higher overtones). A good word for it would be rumble. A bad word would be boom (boom happens much higher up).-Unquote- A nice sample with an amazing deep bass is http://www.amazon.fr/Fabuleuse-Histoire-Swing-Michel-Jonasz/dp/B000F39MI8/ref=ntt_mus_ep_dpi_7Disque 2 - tune 2 Joachim |

Joachim, have you experimented the same kind of problems as Coen with his "dirty" cable?. I mean, have you had any problem with your YFS USB cable, or you find that it works fine and the music is sounding as good as when you tested it for the first time?
Regards,
Juan
Hello Juan, I did not face any problems until now, and the SQ is better than before. The YFS cable remains in the system. I'm not using any tweaks for the MB (which is at least 3 years old) within XXH, minimize OS only. Sincerely Joachim |

I my case with connected shield and powerline, the esd chip was blown. Iow the 5V protection was short circuit to ground. Somehow a current from the pc to the NOS1 ground was created. Cause onknown. At first I thought about the pc, but it was more likely that the nos1 amplifier had something to do with it. So far i did not investigate this any further. I have the habit of disconnecting the NOS1 when i do something to either the pc or amp.
Regards, Coen
P.s you need special equipment and some precision skills to repair the board.
Thanx Coen, ok, following your procedure of disconnecting ........., the best SQ is what we are looking for. No risc, no fun. (It might happen, that I have to go to the post office in the near/next future) Joachim |

Joachim, would be great if you could make a cheap cable like Coen΄s to compare it with your YFS USB REFERENCE - DATA ONLY CABLE
Regards,
Juan
Hello Juan, sorry, I do have some skills in gardening and assembling rough mechanical parts, but not ............. . Kevin from YFS gave me the advise to buy the reference cable, because .............. . I'm not quite sure how to proceed after Coen's remarks in his last post. What can happen. Blown fuses "only" or other severe damages (chips)? kind regards Joachim |

I also have a concern for esd safety that I have to reason out. I HAVE to add that Coen is concerned for good reason; Coen had is ESD protection blown once. Reason : some shortcut at the amplifier side. Only two weeks back there was another case of this, with the exact same reason. And while Joachim is in this topic anyway : Joachim, you too experienced similar (well, reason unknown) but that was with the old NOS1 (non-USB) interface. All I can add to this that I still have a couple of emails about again amplifier "strangenesses" which blew the fuses in the NOS1, right ? Now guys, please don't ask me where the currents will all flow to -and without blowing fuses first - when you eliminate the ESD protection. So know what you are doing, and when things turn out badly it can really imply a lot of $$$ to repair it. Peter Peter, Over the time the Swedish USB2 cable causes strange readings at the NOS1 VU meters and blown fuses for 2 times, and initiated some shutdowns of the new poweramp (with a very fast reacting DCC offset protection) too, and so I went back to a shelf cable. The shelf cable shows no electrical anomalies at the VU meters (after a PC closing down) anymore (and no power amp shutdowns since then) and the SQ was nearly identical to the previous Swedish cable. After reading Brians post about the YFS cable
. At present I hear that the acoustic bass (from Brian Bromberg) has a smaller body, less low resonances, but very pristine (nearly identical to Brians impression). The definition of the music improved a lot, more fine details. http://www.amazon.com/Wood-Brian-Bromberg/dp/B000FQJPBO/ref=ntt_mus_ep_dpi_5 |

Ok Joachim. Thank you !
Can you now please describe the changes in sound with all the detail you can come up with ?
Thank you again,
Peter
Hi Peter, I'm not finished with all of my reference recordings (99% is Jazz), but the first impressions are: Sound is much more analog, MUCH less harshness of the cymbals, less reverberation (especially the mids - piano) in my room, more definition (resolution) in the mids and and highs (delicacy), bass is a little bit more accentuated and tighter, soundstage presentation improved, resinous of violins improved with more body of the instrument. This cable is worth any cent/pence. kind regards Joachim [Edit]: The harshness in the highs was emphasized by a new poweramp (with a DC offset protection), which Im using to omit the preamp now. |
