One widely-quoted exception were the HH Scott integrates; I have yet to actually spend much time listening to the phono section of one, though - and I have never attempted to tweak one. I have been very happy with my Seduction (which is BOTL, lacking even the C4S mods, although I did retrofit the shielded power transformer a couple of years back - not shown in the cheesecake photo below). My only quibble (which is pretty minor) is that I could use a little more gain than it has.

A passive EQ network is not similar. It may sound exciting and even refreshing but you must realize the time space continuum is changed. Long live active feedback phono EQ. RE: the Fisher phono section aint all that what ? What is wrong with tried and true active feedback EQ ? - Eli Duttman 18:28:33 12/02/10 (1) Audio Asylum Thread Printer unarguable. Now, if you want to tell us how you hear something better with passive EQ preamps, we can discuss these sonic matters. Plus, since the hobby/obsession/profession requires subjectivity, we are all entitled to our sole opinions. Nobody can take away anybody elses listening enjoyment, right ? Somewhere, within your constant recommendation of this RCA passive EQ updated circuit, I sense you are trying to help some of us enjoy our systems even more, right ? Please explain how this passive unit betters active units, from a listening concern ? Passive preamp stages change the time constants recorded in most stereo era discs, because most stereo discs were encoded/recorded with feedback EQ. You may enjoy that changed sound; thats cool. Passive EQ tubed preamp units tend to be noisier and tougher to achieve high gain, compared with their active feedback competitive preamps. I have tried many types and still prefer active feedback EQ. When you can prove to me that passive sounds better, Ill change my tune. Different, yes; better, no. Downstream drive ability ? What downstream drive ability is your concern ? We are talking about a phono stage, inherently requiring more gain downstream to interface to a power amp stage. Nobody connects any phono stage directly to a power amp. At the very least, there is padding with a volume control and/or balance pot or resistors. Most of us presume the use of a line level preamp gain stage after the phono stage. We are not afraid of another simple gain stage, are we ? Your Audio Asylum Thread Printer 5 of 712/19/11 10:25 AM tweaked RCA phono stage even uses another gain/buffer MosFet stage ? Why go solid state ? Does it sound better ? Can you describe its sound ? Can you describe the sound of the RCA passive phono stage with or without the MosFet ? Have you built this recommended phono stage which you tout highly ? You seem to spend alot of your time and energy researching via a sampling program ? Does your sampling program have ears ? Can your program tell you how something will sound ? Or, is it a crutch for seemingly technical mastery ? Do you bring this program with you to listen at friends systems ? or to audio stores(if you can find any anymore.)? I am not trying to attack you. I do realize your good intentions. So, please describe the sonic benefits of this RCA passive EQ phono stage, or any passive EQ tube phono preamp stage, compared to known acceptable active feedback EQ phono stages ? Different sound ? Yes. Inherently better sound ? You know better. Post a Followup: FAQ Post a Message! Forgot Password? Moniker (Username): Password (Optional): Remember my Moniker & Password (Whats this?)
