A friend of mine brought this to my attention. It would seem that the NAD S300 integrated amp from their Silverline series is no more and no less than a Gryphon Tabu Century integrated in a different box with different toroidal transformsers. The NAD S300 costs around £1500 whereas the Gryphon (no longer available) cost around double that 
Don't know the whole story but if anyone knows it would be interesting to find out more. Seems like the S300 was designed and built in Denmark (home of Gryphon) with Gryphon acting as "consultants". The extent of their "consultancy" seems to have meen merely to recyle their no longer in production Tabu integrated! The one concession made was that where Gryphon alwyas use C-Section transformers, the NAD uses Holmgren toroidals. Apart from that (and the case of course) they are 100% identical.
The specs are identical:
- True dual-mono (separate toroidal xformers for each channel)
- 100W into 8ohms, 200W into 4ohms and 300W into 2ohms.
- balanced inputs
- Zero negative feedback circuit topology
- Separate power supply with own transformer for all non audio circuits
I can't find a pic of the inside of either but I suspect that they would look identical. The cases, whilst different have clearly the same layout of buttons and same basic size:

(NAD have been having bandwidth issues with their site so aren't allowing linking of images directly, you'll have to click on the link)
NAD doesn't mention any of this on their site but that may be part of the agreement they had. The Gryphon Tabu was extremely well received with critics rating it amongst the best (if not the best) integrated in the world. So, is this NAD an undiscovered hifi bargain (of the Century
) ?
Said friend had been listening to it in his system and comparing it with his MF A1000 and has been pretty impressed
