Our English Synopsis 1. Audio Culture (Editorial Notes) Litmus test: how many carats qualify for being a Golden Ear? Is there such as a thing as an infallible Audio Guru? Conclusively is there a sure basis for comparison for amplifiers and speakers? If there is no such thing in classical music what about pop? Tolerance in equipment can be measured in percentages or less, Plus-Minus, mostly in one dimension. For an audio critic tolerance in judgement is much greater and in more dimensions, depending on the agility of the soundman, the jury's taste, what is the audience'expection etc. 2. Soundservice Space for those desiring to inquire, needing advice, wishing to comment or argue or even advertize. 3. The Anatomy of Crescendo Hi-Fi fans light-heartedly juggle with 60-70 dB. How far should real dynamic range extend in recordings? In Beethoven's 5th symphony for instance, in the transitional attaca with its rousing crescendo? Testing 14 various recordings we could not find a greather 30 dB difference between pianissimo and fortissimo. Such 30 dB could be found on Toscanini's 1939 recording as well though some recent stereo recordings had a range of no more than 20 dB. 4. Stringserenade in Double Digits The first domestically produced digital (or hybrid) record. The program has been recorded on Sony PCM 1600. We can soon pass judgement on sound quality. Program consists of Tschaikoswky's Stringserenade and Dvorak's Serenade. 5. Magic Flutes of Half a Century Discography of Mozart's opera. 6. Recording Sheet Reviews, criticism. 7. Tower a2-f2 Chess move by Videoton? Not really, this is a Hi-Fi tower, the letters and numbers stand for a cooperation. Two components (tape recorder and recordplayer) are provided by Akai, two further links (tuner and amplifier) are manufactured in Fehérvár. A promising step in the Far-East Opening. 8. Home Recording - Studio Recording The lion is a kind of cat, smaller in size but the specs are similar. This is the way with smaller and larger recorders. Are they of the same species? If not, when have they diverged in their course of development? That was the subject of conversation in the Mechanikai Laboratórium, the domain of Hungarian studio recorders. Illustration: Akai GX 4000D, Revox B77 and the ML STM-600 studio recorder, with their main components, parameters, standards. 9. The Yellow Brick Road (Press digest) HiFi Stereophonie, HiFi News & Record Review, Audio. 10. Black Power Our Playmate of the Month is not a pretty receiver, not an attractive feminine cassette deck but the very embodiment of masculine power: the Harman-Kardon Citation 16 power amplifier. The Hungarian Radio is using this type in their musical studios. Our measurements are substantiated by subjective listenung as well. Comparison: Quad 405 and Radford STA 25 (tube) power amp. 11. Disorder of Cable (Impedance and signal level) Lets make order in the jungle of wires and couplings. 12. Orion Tower II. Modifications before mass production on the Orion equipment presented in our previous issue. 13. How Many dBs Rumble? Depends on how it is measured. Starting from now our test will be fivefold on the recordplayer's rumble. 14. Presenting Three new recordplayer (Tesla MC 400, Pioneer PL-100, Akai AP-30D), one RIAA-preamp and Videoton Aida receiver with speakers. 15. MOD By mass acclimation we will try to mare the well distributed, very cheap dubiously Hi-Fi Orister amp presentable. 16. Between Takes (Forecast)
