I have been an audiophile for about 20 years. I upgraded my audio system continuously in order to find the most natural sound. However, it was very difficult to get natural sound equipment. I tried Solid State amplifiers (Mark Levinson 27L) and a Threshold FE 10 line- and phono preamp with B&W801-3 loudspeakers. This system was detailed and well focused but too hard and sharp. I prefer warm and relax sound.
I changed to a valve preamp and power amp but I didn’t used these with the B&W 801-3 loudspeakers. I tried it with the TP1 London with a Lowther PM2A. The sound was very warm and relaxed but the bass was disappointing (somewhat loose and too delayed sound). So I looked into other type loudspeakers and decided to get horn a front horn.
I found the Oris 150 horns at Bert's website. I bought the Oris 150 horn and got the AERal driver from the Korean dealer (Mr. Yun). I added modified LaScala's (10% bigger size) with Altec 515C alnico woofers for the bass.
The Oris horns played on a handmade 300B tube-amp and the LaScala's are driven by handmade AD1 tube-amp using low pass passive filters (160Hz, 6db: consist of Solen fast cap’s and ribbon type air cores). My whole system is very transparent, dynamic, delicate, sweet, warm and lovely to listen too. I strongly would like to recommend the Oris 150 horns and the LaScala's system.
My system, for the record:
