== Kurzbeschreibung ==
 
Top-Modell von Aiwa zu Beginn der 90er-Jahre in der Vor-Sony Ära. Wurde zumindest 1992 und 1993 mit der Zusatzbezeichnung "Evolution Series" verkauft. Klanglich durchaus ansprechendes Gerät, welches sich vor der Konkurrenz nicht verstecken musste. Hatte damals keine Lobby, hat heute keine Lobby – ein Segen für den Gebrauchtkäufer.

der XA-950Z qualitativ in etwa einem mittleren Sony ES-Amp (5er oder 6er) entsprechen. In etwa,denn es

fehlt doch etwas an der Solidität und haptischen Qualität eines ES-Amps,aber das hört man ja nicht.

Der Phonovorverstärker ist zwar ökonomisch aufgebaut aber eben doch kein "afterthought" wie bei Amps von

* [[Aiwa XA-008]]
z.B. Yamaha (5er) oder mittleren Kenwoods aus der Zeit und bauteilemäßig qualitativ eine Stufe besser bestückt
+
* [[Aiwa XA-950]]
wie z.B. ein Sony TA-F400 (oder ein TA-FA3ES/TA-F5xxES).  Die Endstufen sind ein SIPP-KISS-Design mit der Kombi 2SC2922/2SA1216,durch-
 
gehend bipolar bestückt und von einem recht weichen Netzteil versorgt. Die Spannungsversorgung
 
der Phonovorstufe durchläuft übrigens zwei aktive Filterstufen. Man hat sich also im Rahmen eines engen
 
Budgets hier durchaus Gedanken gemacht was wohl lobenswert zu erwähnen ist da keinesfalls selbstverständlich.
 
Die Opamp-Bestückung in der Vorstufe besteht durchgehend aus NJM2068D-Typen,was vergleichsweise hochwertig ist
 
und deren Speisung überschreitet nicht ± 15V.
 
Wie Eingangs erwähnt ist der XA-950Z ein durchaus ansprechend "klingendes" Gerät im Werkszustand und bietet
 
klanglich gehobenes Mittellasseniveau ohne werbewirksame Materialschlacht. Aus heutiger Perspektive kann mit
 
modernen OpAmps und einem selektiv-spezifischen Bauteileupgrade da realtiv easy noch einiges gemacht werden.

Reviews[edit]

  • Top of the line model from Aiwa in the early 90s in the pre-Sony era. Sold at least in 1992 and 1993 with the additional designation "Evolution Series". Sound-wise quite appealing unit, which didn't have to hide from the competition. Had no lobby then, has no lobby today - a blessing for the used buyer.

The XA-950Z was Aiwa`s top-of-the-line integrated amplifier at the beginning of the nineties and came off the production line at the then Aiwa Technology Park in Newbridge/South Wales. Which makes it "Made in UK", but of course the amp is clearly a Japanese late eighties design - with that certain likeable Aiwa touch. If the line driver wasn't also an opamp stage but a discrete Class-A circuit, the XA-950Z would be about the same quality as a mid-range Sony ES amp (5s or 6s). More or less, because it lacks a bit of the solidity and haptic quality of an ES amp, but you can't hear that. The phono preamplifier is built economically but is not an "afterthought" like amps from e.g. Yamaha (5er) or middle Kenwood's from the time and qualitatively a step better equipped like e.g. a Sony TA-F400 (or a TA-FA3ES/TA-F5xxES). The power amps are a SIPP-KISS design with the 2SC2922/2SA1216 combo, bipolar throughout and powered by a fairly soft power supply.
