I started this hobby about thirty years ago, but I did not have the budget necessary for an excellent sounding system. Today, I developed my own system based on individuality and the actualisation of my own ideas. 25 years ago I analysed several constructions and learned that the two main reasons for bad sounding systems were the high complexity of electronics and the crossover topologies. Other reasons I often came accross were the mediocre quality of electronic components and the neglect of several details such as vibration, materials involved, magnetism, distortion spectrum etc. Those years the magazines " l'Audiophile ", " Wireless World "and several articles written by Jacques Mahul, Jean Hiraga, Siegfried Linkwitz, L.J.S: Bradbury, Roy F. Allison influenced me very much. Then, as 23 year old I designed and built my first set of electronics: the Preamplifier No.1, the Active X-over No.1 and the FET Class A Power Amplifier No.1. This Power Amplifier has been produced for several music enthusiast and colleagues. Today, after 22 years some of these power amplifiers are still in use and according to the owners they perform much better than many high rated commercial amplifiers. Up to now I have built this and that as you can see on the list below. My last project has been the Fullrange TML Speaker No 3 using Manger's Bending Wave Transducer MSW. In my opinion this transducer is one of the best loudspeakers ever made in the frequency range of 150Hz to 24kHz. Unfortunately, the Hi-Fi community still does not pay enough attention to the MSW. I am very lucky to have enough space for the equipment: The room dimensions are 2.4m x 5.6m x 3.6/6.7m (35 m2) . WAF has never been an issue, I assume it's due to the fact that I always tried to design the equipment as elegant as possible. I listen to many styles of music, which comprises approx. 25% classical, 30% jazz and 45% rock, pop and electronic music. Evaluation LP's and CD's:

No.3 Marco's comments about his System: AA: "Marco, how would you describe your system's sound?" MR: "In my opinion, the most important quality of a system is that it conveys emotions and you are able to forget the loudspeakers. Normally I do not like descriptions like slow, fast, depth, tight, harsh and whatsoever... I will have a go! Think of the micro dynamics of a horn speaker driven by a tube amplifier, the coherence and sound resolution of an electrostatic speaker, the bass of a medium-sized two way speaker driven by a solid state amplifier and the holographic sound reproduction of a single fullrange speaker - that's it, a nice emotion mediator system!" AA: "Do you think there is room for improvement?" MR: "Yes of course, generally speaking, there is always room for improvement! Although my system has been in a permanent evolution and improvement process I cannot imagine ever stopping to initiate changes. I do not feel the urge to force any major changes immediately. I am pretty happy to enjoy the music. " AA: "Have you got plans for upgrading?" MR: "I always produce
numerous ideas and possible upgrades. Therefore, for me the
question is rather a rhetorical one. Yes, there are lots of
plans but I have no idea how and when I will start to tinker
with my system. However, to be honest, I have some plans to
improve the clock part in the CD player again and to play
with additional damping techniques on the speaker system
