I have a TDL 4010. It is a great unit but they stopped making them a few years back. KAB makes a nice one that is reasonably priced. Tempo keeps saying they are going to come out with a couple but it may be a wait! Fehlauer has good reviews. The Sentec 10 also though the Sentec 11 is a big step down in terms of utility. Graham Slee but some may be put off by its looks. (Like me!) |
jollytinker Anyone know what nartb stands for?National Association of Radio & Television Broadcasters - the predecessor of the NAB. |
My old Scott 299 integrated amp has two phono settings - "riaa nartb Ortho" and "euro 78." Its a wonderful old school amp that my grandfather bought when it first came out, and I later spent years listening to it at home as a kid. Anyone know what nartb stands for? Also the fehlauer monophonic phono stage is built specifically for this purpose and is wildly adjustable, and comes with suggested settings for an exhaustive list of early record companies. As the title says it's only in mono though. |
I am indeed asking about photostages/preamps that offer different curves than RIAA. I have some European pressings from some of the great orchestras and conductors of the 20th century that frankly sound awful with a standard RIAA curve...no bass, ear piercing cymbals, ect....as an avid classical music fan who seeks out artists of this era as examples to get us closer to the composer's intention (like when you can get an interpretation or student or two away from the original), I would like to be able to make these albums "listenable". Thanks for your continued options 'Goners! |
If you play lots of records made before the RIAA curve became the standard, such flexibility is useful, even necessary for historical archiving. Otherwise, it only introduces extra switches, components and solder joints that can degrade SQ. I once rebuilt a Quad 22 preamp, which offered several curves — I never used them so I stripped them out. I ended up with almost a meter of wire, in many little 1- and 2-inch lengths, plus several switches, little caps and resistors, left over on my bench — and a far better sounding preamp. |
@chakster this recent review illustrates the value of multiple curves to suit the way specific records were cut (nothing to do with loading) https://positive-feedback.com/audio-discourse/gold-note-ph-10-phono/ |
