Tubes add color, and at the mastering stage, I would not want that from the amp. I would want a clear clean transparent amp. |

The best ones are not "euphonic," and are clean clear and transparent! DC |

Yes, thats what i thought. without having the experience my self i was told by a few tube gurus that a well designed tube amp will not sound like "tubes" at all. Ed |

I think a lot of that comes from the guitar amp thing, tube amps versus solid state, "that tube sound", so they apply it to all power amps. It's been my experience that most tube power amps with the typical gain control and nothing else, are transparent when the tubes are maintained. |

I was just curious if everyone here shared my gut feeling that tube amps don't have a place in the mastering studio, and it seems that most agree with me that save a few exceptionally well-designed (read expensive) models, we're all better off with solid state amps. |

Two problems with the tube amp HEAT and it cost $7500.00. |

Threshold s350e here. Older, but solid [no pun intended] and was a good deal. As a side query: anyone listened to the 'new generation' 'digital amps', such as the PowerPhysics modules (used by NHT in their corrected/powered setup) or similar? Rumor has it that this technology has matured and is on par with the better class A or A/AB amps.......although previously more or less confined to trunk-rattler car stereo installs..... |

In 1985, de Paravicini introduced his new record cutting system. Now installed at ‘The Exchange’ in the heart of London, (originally Island Records ‘Sound Clinic’ facility). This is phase corrected, and uses in excess of 1,000 watts of tube audio power, based on the classic EAR 509 circuit. |

The "warmth" in a lot of tube electronics is due to their dismal top end, the bad transformers they use, and the loading down of their high-impedance outputs. Because of the output transformer and the feedback used, many tube circuits have a partial bass instability that gives a bloated bass. Any warmth in the tube sound is a defect, but listeners don't want to know that. I don't have to use tubes in my designs; I only do it for marketing reasons. I've got an exact equivalent in solid state. I can make either type do the same job, and I have no preference. People can't pick which is which. And electrons have no memory of where they've been! The end result is what counts. |

Does anyone know of any mastering house that uses tube amps on their mains (not a lounge or secondary system)? I seem to remember one of the guys at Precision had some Manley tube amp on his mains. Last time I was there, I forgot to ask. Since the tube category seems to be such a minority in this thread, I'm curious as to which places can be used as examples. |

Greg uses Audio Research. I think Doug still uses his Sherwood Sax on the mains. I was bi-amped with Sherwood's for a long time, but the change-over to surround has forced a change. I'm now on Spectrals. 10 sets of tubes each year was a little rough to swallow even on Sony Dollars. My bud down the hall, Vic Anesini is on Sherwood's Bi-Amped. |

The amp I ended up with is a "bel canto eVo 4" (I run mine in bridged mono, the eVo 4 has 4 mono channels at 150W). Funny enough bel canto got their reputation by building valve (tube) gear. http://www.belcantodesign.com/prod_evo4.html Thor |

That's it! Bel Canto was the amp I favorably reviewed when I was putting it up against the Pass. It's a very good-sounding amp. The Pass is better, but you're paying for a LOT of BEEF! |

Four years ago, after an AES tour of the Sony facility, you were kind enough to sit me at your mix posotion and play several tunes - Toto, Africa- (Maybe you remember I lost it!) Miles, Kind of Blue etc. As I recall, you were usind Dunlavys, Cello Pallette, Millenia, Meitner? your sound raised the bar on my expectations considerably, and enabled me to up my game several notches. THANK YOU! What is your current setup, if you please. Mike Chafee |

With the talk of ?digital? amps I thought this might be of some interest: Some of you know Bruno Putzeys from his DSD Converter, Grimm Audio, etc. Not sure if you know of the amplifiers he designs? The Hypex UcD (Class D) is eminently suitable for mastering?just ask him. His primary design goal was full-range neutrality/transparency so they have resolved the few areas problematic with most other Class D (Tripath Bel Canto, etc). There is a pile of info on this?but I won?t bore you. Hypex amps can be used in either ?active? speaker applications, or as power amp monoblocks. There are three versions, with varying power output. |

This is the data sheet for BP’s Hypex ‘400’ amplifier module (performance graphs at bottom of page) http://www.hypex.nl/docs/UcD400_datasheet.pdf (note, e.g., the THD vs Freq. plot—ruler flat) |

I know you are a perfectionist, and wonder if you could describe the differences the amplifier changes have made in your system. |
