Top-model of Aiwa at the beginning of the 90s in the Sony Era. Was sold at least in 1992 and 1993 with the additional designation "Evolution Series". Quite an appealing device in terms of sound, which did not have to hide from the competition. Did not have a lobby then, does not have a lobby today – a boon for the second-hand buyer.

The XA-950Z was Aiwa 's top-of-the-line integrated amplifier at the beginning of the nineties and rolled off the assembly line at the then Aiwa Technology Park in Newbridge/South Wales. What makes it "Made in UK", but of course the amplifier is clearly a Japanese eighty-something construction - with a certain sympathetic Aiwa touch.
If the line driver were not also an opamp stage but a discretely constructed Class-A circuit, the XA-950Z would correspond qualitatively to a medium Sony ES amp (5 or 6 series). For example, because there is something missing from the solidity and haptic quality of an ES amp, but you can't hear that.
Although the phono preamplifier has an economical design, it is not an "afterthought" as with amps from Yamaha (5 series) or medium-sized Kenwoods from the time and is one step better equipped in terms of component quality, such as a Sony TA-F400 (or a TA-FA3ES / TA-F5xxES). The power amplifiers are a SIPP-KISS design with the Kombi 2SC2922 / 2SA1216, equipped with bipolar throughout and powered by a fairly soft power supply. By the way, the voltage supply of the phono preamp passes through two active filter stages. So, within the framework of a tight budget, one has certainly thought about what is probably commendable to mention here, which is by no means a matter of course.
The opamp assembly in the preamp consists of NJM2068D types throughout,which is comparatively high-quality and their power supply does not exceed ± 15V.
As mentioned at the beginning, the XA-950Z is a quite attractively "sounding" device in factory condition and offers an upper middle-class sound level without an effective material battle. From today's perspective, a lot can still be done relatively easily with modern OpAmps and a selective-specific component upgrade.
