LessLoss Firewall Current Conditioning Unit

Introduction Mains conditioning is often an essential tool in achieving good results from quality equipment, unless you happened to be blessed with good mains power. You have transformer based solutions, such as isolation or balanced power transformers. You also have capacitor based filtering, which tackle a certain frequency range based on the tuning of the circuit. There are also other approaches such as choke filtering and power regeneration.   Description The LessLoss Firewall Module uses the company's proprietary skin filtering technology first seen in their power cords. The wire surface is treated to allow the mains frequency to travel through efficiently (50 Hz or 60 Hz as the case maybe), while attenuating high frequency noise. Since no capacitors are used in the process, there is no limiting of current. The LessLoss Firewall Module (hereinafter referred to as "Firewall") is available in two versions, a module with C13 and C14 connectors, and a module with screw t

Thiel TT1

Introduction I saw the Thiel TT1 some time back at Sound Decisions, the local dealer for Thiel. The company has with a change in management and ownership, taken a very different direction with it's products. I made an appointment with Sammy Low, principal of Sound Decisions to have a quick listen to the TT1 sometime later. Description The TT1 bears little physical resemblance to past models. The TT1 is a four drive speaker in a slim rear ported enclosure. High frequencies are handled by a 1 inch titanium dome tweeter, while a 4 1/4 inch fibreglass cone handles the midrange. Low frequencies are taken care of by two 6 1/2 inch aluminum cone woofers. Frequency response is stated as 39 Hz to 30 kHz (no limits stated), while in-room sensitivity is rated at 90 db. Impedance is specified at 4 ohms nominal and 3.67 ohms minimum. The drive units are not Thiel's in-house designs - according to Thiel's official website, the woofers are produced by Scanspeak to Thiel's specificatio
