Manufacturer: Musical Fidelity (Audio Tuning Vertriebs GmbH), Margaretenstrasse 98, A-1050, Vienna, Austria. I am selling this as a set, as it is made for each other: "Match in audio heaven!". Both units are brand new, unused, I only opened factory sealed boxes for purpose of making photographs, and to check if I haven't received something wrong from seller I got it from (shop in Italy). Both items come with invoice from this reputable shop, providing 12 month guarantee for both units. As there was a lot of reviews and texts about both of them, let me just point out that this is brand new version of legendary British amplifier from company now in ownership of Austrian Pro-Ject. Speakers are completely made in Austria, in highest possible standards, even higher than BBC's original ones. Reviewers that have checked interior and crossover all confirmed that only the best possible materials have been used in this line of speakers. Selling because it is a surplus. Same as I can not eat two lunch I ca not listen to two systems in same time, so I decided to put this on market, not giving it a chance. I am sure I would be tempted to keep both, but my room is already overcrowded. If you see any marks on my photographs on the speakers or amp it only from traces of packing material, my hands, or dust. Both are unused and brad new products!! I am sure, whoever takes this from me will have some magical musical journeys ahead in very near future!!
