Audio Analogue Donizetti Anniversary Power Amplifier

The only thing in common between this new model and previous versions of Donizetti remains the name, while the project and the technical solutions used are completely new. It is a high power stereo power amp: with its 250W@8Ω that doubles halving the impedance is able to perfectly drive any loudspeaker. The amplifier has a complete dual-mono configuration starting from the two 1200VA toroidal transformers specifically designed for low dispersed flow. Uses our SeGeSTA (Single Gain Stage Transconductance Amplifier) configuration followed by a group of four transistors to provide all the necessary current without affecting the gain stage performance. The amplifier does not use global feedback. The 4-layer printed circuit has been designed so that the input signal never crosses the output signal and that the sensitive amplification stages are as far from the power transformers as possible. All components are of the highest level, starting from military standard resistors to continue with the capacitors on Airtech specification up to the wiring made of 7N OCC copper and to the pure copper and gold-plated connectors. Donizetti Anniversary is available in silver and black. Donizetti Anniversary can also be used in mono configuration, achieving even more extreme performance, just think of the output power that reaches over 1000W on 8Ohm impedance.

Zero Global feedback, all stages fully balanced, dual-mono configuration and discrete components circuits, power stage with 12 bipolar transistors per channel, 56000μF filter capacity per channel, oversized military resistors to minimize thermal distortion, "audiograde" capacitors on Airtech specifications, microcontroller management.

We endeavour to despatch same day for orders placed up to 2pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.

UK ORDERS:  We despatch the bulk of our UK mainland items on a 24 hour service – Free of Charge.  Non Mainland locations - Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer and are not Free of Charge. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS. 

INTERNATIONAL ORDERS: We offer competitive rates which can be confirmed by email. Please just ask – we will need a full delivery address and telephone number. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Hifisound or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

COLLECT IN STORE OR HOME INSTALL:At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
