The new NVA INT400 Integrated amplifier is handmade in the UK, and features an all new 'easy care' satin-matt acrylic case, and a 5 year (first-user) warranty. The change to a wider, deeper format has allowed for uprated power supplies and a more generously spaced layout for optimum signal purity. With 400va on tap and a premium volume pot fitted, this is the best sounding integrated amplifier that NVA has ever produced, and is compatible with a wide range of speakers.

  • IMPORTANT - there is no protection circuitry or filtering on the output of our amplifiers (that's one of the reasons why they sound so good!), so care must be taken in use. Do not short circuit the output; doing so will fatally damage the amplifier boards. Do not use high capacitance speaker cables as these could damage the amplifier by creating a virtual short-circuit at high frequencies. Do not use bi-wiring with non-NVA cables. Do not use Litz, Goertz or woven cables. Do not twist cables together. Avoid cables with a capacitance of greater than 200pf per metre (failure to do so will invalidate our warranty) and do not use non-NVA cables over 10 metres in length. The best sounding speaker cable for NVA  and the perfect electrical match, is our LS series of low capacitance cables. Proof of purchase of NVA speaker cable, or another suitable low capacitance speaker cable, may be required when submitting any NVA amplifier for warranty repair.
