NVA A20 Stereo Amplifier
The NVA A20 is a compact hi-fi amplifier designed purely for the best and most satisfying musical reproduction. It is designed to partner the P20 pre-amplifier to form an entry level NVA pre/power system but can be used with any NVA pre-amp.
Clear, detailed, musical, atmospheric, sweet nature and absolutely NO harshness or grain whatsoever. Bass is light and agile and the amp seems to be quite happy at all volumes.

The A20 is a 20w stereo power amplifier designed to be used with a passive pre-amp like the NVA P20 but will work OK with active pre-amps or direct feed from a DAC or computer audio system with volume control. It should only be used with NVA low capacitance speaker cable and NVA low capacitance interconnects. Use of other speaker cable invalidates our warranty.
Warranty is for two years parts and labour and after that a further three years it will be repaired on a no profit / cost basis.
Available in 120v or 240v please stipulate on purchase.
NVA AMPLIFIERS AND SPEAKER CABLES – WARRANTY
Only NVA LS1, LS2, LS3, LS5, LS6 and LS7 is recommended for use with this amplifier, other cables will invalidate the warranty.
For best sound the amplifier should be left powered up. Electricity consumption is very low. It is for this reason that the power switch is located on the back panel, where it may not be easy to reach. Turn the amplifier off when you do not intend to listen to it for extended periods.
NVA amplifiers are unique, and one thing that makes them so is the minimal compensation for the output stage. It is very possible to send this amplifier into oscillation by connecting too large a capacitive load on the output, the usual culprit being unsuitable speaker cable such as Litz or Goertz type constructions.
If you insist on using other cable (this will invalidate warranty) please ensure it is no more than 200pf per metre and it should not be used in lengths over 10 metres. If you wish to Bi-Wire this can only be done with NVA cable and they can be made that way on order for a small added cost.
For design performance only NVA Sound Pipe, Super Sound Pipe or Sound Cord Interconnects should be used, but this is for sonic as opposed to safety reasons.
