| | + | Das KX-7030 gehört zu jener Generation in der man die Produktion guter |
| | + | Wiedergabequalität auch in Leichtbauweise und mittels hochintegrierter |
| | + | Schaltungen ganz gut im Griff hatte. Ich habe selbst einen KX-7030 vor |
| | + | einiger Zeit erworben der sich wohl beim Vorbesitzer fast kaputtgestanden |
| | + | hat. Es läuft mittlerweile einwandfrei. Die Klangqualität die das Deck |
| | + | bietet liegt irgendwo zwischen einem TC-K 690 und TC-K 770. Was ja absolut |
| | + | gesehen schon sehr zufriedenstallend ist. Als Dragonkiller oder als qualitäts- |
| | + | äquivalent zu einem GX95/75 würde ich es aber nicht bezeichnen. Es ist ein |
| | + | Deck der oberen Mittelklasse und kein Spitzenklassedeck. |

| − | * The KX-7030 belongs to that generation - at the beginning of the nineties - where the production of good playback quality even in lightweight construction and by means of highly integrated circuits was well under control.
| |
| − | * I bought a KX-7030 myself some time ago, which must have almost broken down at the previous owner. It now runs flawlessly. The sound quality, which the deck originally offers, lies somewhere between a [[Sony TC-K 690]] and TC-K 770. Which is already very satisfying in absolute terms.
| |
| − | * But I wouldn't call it a dragonkiller or the quality equivalent of a real top deck.
| |
| − | * It is an upper middle class deck and not a top class deck from that time.
| |

| − | If you know how to use a soldering iron, you can get a bit more playback quality out of the unit by replacing the numerous coupling electrolytic capacitors in the signal paths with e.g. Nichicon bipolars (the green ones, not expensive). The filter capacitors in the power supply branches should also be replaced. Replacing the ceramic capacitors with foil types of the same value will also have a positive effect. If you are still recording to tape, you should replace the NJM4565DD in the recording branch with an NJM2068DD. Which, however, requires a recalibration of the recording branch.
| |
| − | * Overall, a KX-7030 so revised then comes across as subtly better, smoother, with better resolution and contouring.
| |
| − | * My tapes recorded with a TC-K 770 are now sonically reproduced 1:1 by the KX-7030. Replacing the Toshiba opamp can be avoided if you increase the quality of the components around it a bit. Of course, provided that the azimuth is correct and the audio heads are demagnetized.
