Citeva decupaje scrise de Arturo Salvatore

- No properly designed and optimized system requires an active Linestage / Preamp - preamplifiers came into existence to equalize and amplify the very low-level phono signals from a turntable. Most tuners and tape decks had their own volume controls, and didn't need a preamplifier when used on their own. Also, many power amplifiers had their own volume control. After CD players became popular, and turntables became relatively rare, preamplifiers became (theoretically) "obsolete" and/or "redundant -They could have placed the line-stage directly within the CD players themselves, which would have been more convenient, economical and even have saved the cost of an extra pair of cables (a sonic benefit too). They predictably didn't. Why? Profits.
In a CD system (or tape, tuner etc.), the analog* outputs must be directly connected to the amplifier(s). There is a much greater chance for this scenario to succeed compared to a phono system. The fact that it still fails, in many (if not most) cases, is because the analog stage of the CD player (or DAC) is not properly designed.

In many instances, this "failure of design" is done on purpose. The reason is to force the owner to purchase a separate linestage, hopefully from the exact same manufacturer of the ill-designed CD player or DAC. ("Sir, don't overlook brand name compatibility!")

- personal nu sunt de acord cu ceea ce spune si consider ca se inseala sau se insela la momentul cand zicea asta. Cred ca sunt extrem de putine surse cu output variabil care sa poata livra semnal corect catre un power. La randul lor, etajele de putere nu stau bine pe parte de impedanta input. Dar poate ca e o conspiratie asa cum spune in continuare ? :D

Poate ca asa e in multe cazuri, defapt fara indoiala, dar, care sunt exemplele de surse cuplate direct in power care rup gura targului ?! Personal nu le-am gasit, dar poate nu am cautat destul si nu am vazut destule. Insa un lucru imi este cert, cu cat incerc mai mult sa gasesc asa ceva, cu atat imi dau seama ca fara preamplificare nu se poate sui catre straturile superioare ale Nirvanei.

Si defel nu prea cred in conspiratii mondiale. Ba mai mult, sunt convins ca daca ceea ce zice omul asta se putea, se facea. (ma refer la acele minunate output stage cu volum variabil care sa faca inutila existenta unui pre).

Si ce folos ca teoretic se poate, hai se vedem daca si practic exista ?!

Dar un mag bagat direct in power amp ? Ar trebui sa sune la fel de bine ca si prin preamp, daca suna diferit prin preamp ar insemna ca sunetul este colorat !

nu am avut niciodata un alt soi de magnetofon decit akai, dar toate akai-urile care le-am avut aveau iesire NUMAI variabila (valabil si pentru majoritatea deck-urilor de pina la jumatatea ani 80). ciudat in contextul ideii de mai sus cind te gindesti ca akai are daca nu ma insel doar una sau doua perechi de preamplificator-amplificator (dintre care una sigur extrem de rara).
It's the music, stupid!
