Original Owner. Having listened to and owned numerous tube amplifiers this one stands out for speed, transparency, soundstage clarity, dynamics, bass control and lack of any tube glare or excessive bloom.
Additional considerations of the amplifier over my time of ownership is its feature set, gain control, 3 feedback adjustments, multiple inputs, tube longevity and carefree operation. It has been completely and totally dependable with no hiccups during my time of ownership other than once changing out a noisy output tube. This particular ZH270 has several notable upgrades including Audience auricap coupling capacitors, Goldpoint stepped attenuator and Van den Hul silver hybrid wiring. There are also 2 ERS boxes over the small transformers that can be simply lifted off, see photo. All of these enhance performance of the amplifier in notable ways.The wiring offering a notably more refined/relaxed presentation, quite significant over the stock unit and probably the most significant improvement over the stock amplifier. The benefit of the Goldpoint is near perfect channel matching as noted compared to the stock Nobel. This could clearly be seen on the oscilloscope before and after installation. The result of this sonically was greater specificity of imaging, separation of instruments and voices. Having owned the amp and listened to various tubes I can say that they all make a difference but it will be taste and system dependent. I have settled on a quad of Phillips Miniwatt 7062 input tubes which will come with the amp and GE 5 Star 5965 driver tubes. I will also include a full set of Sylvania outputs and 2 extra RCA outputs PLUS a pair of Tungsol 12at7s and a pair of Amperex 12at7’s. You are set for tubes for the next 15+ years conservatively. The Miniwatts have been in the amp about 2 years and test like new. The price is FIRM. Add 2.5% for paypal fees. Shipping included in price to anywhere in the Continental US. I will ship overseas and out of country but all shipping/insurance costs will be paid by the purchaser. Condition is overall excellent considering age but there are a few minor scrapes on the top edge of the unit that can be seen in the photos. Otherwise no scratches or marks on the face or case. I will gladly audition the amp for those seriously interested prior to purchase. I am located in Central Florida. The amp has been in a pet, child and smoke free environment and covered when not in use, very clean inside. See website for technical information.
