Beyerdynamic Tesla T1 and A1 Amplifier Source: Beyerdynamic Tesla T1 and A1 Amplifier | Headphone Reviews & News Blog from HiFi Headphones The new [showUID]=2620&tx_sbproductdatabase_pi1[showUid][backPID]=105&cHash=0d01314f22]Beyerdynamic Flagship model, the Tesla T1, is now available in the UK. We have been lucky enough to borrow Beyer's Demo pair and it was love at first listen. Delivered in it's aluminium flight case the Beyerdynamic T1 is hand crafted in Germany and it shows - they have a solid industrial beauty that exudes high end build quality. The coils are hand wound as a machine is not capable of the necessary dexterity to achieve Beyer's exacting standards. Behind the detailed mesh grilles on the beautifully finished aluminium and plastic earcups, the drivers are fitted to the front angled back towards the ear. The diaphragms are made of two-ply foil, which features low moving mass and good inherent self-damping. The Beyerdynamic T1's skill is a very low-mass diaphragm in a very dense magnetic field of 1.2 Tesla. The result is a crisp, fast and transparent sound with low distortion (quoted at 0.05 per cent). These completely redesigned transducers achieve values of over one Tesla (a unit of measurement for magnetic flux density). The increased efficiency also leaves the T1 with greater power reserves for dynamic, undistorted sound and nearly lossless conversion of electric signals into sound waves. The extremely lightweight 600 Ohm voice coil provides transparency and perfect impulse fidelity. Beyerdynamic A1 Amplifier The perfect partner to the T1, with its unique intelligent-circuit concept the Beyerdynamic A1 is capable of reproducing an amazingly wide frequency range which stretches way above human perception. Underneath the large front-panel-mounted aluminium volume control is a high grade ALPS-potentiometer for smooth volume adjustment. This is just part of the attention to detail that ranges from the outer unit construction to its quality integral components - use of a generously-dimensioned toroidal core transformer, plus a combination of carefully selected components allows even the highest-impedance headphones to be driven flawlessly over the entire frequency range. Our Impressions We felt the sound was fluid and natural, there is a fast sense of detail that is crisp and precise without being fatiguing. The headphones themselves are surprisingly light and in typical [showUID]=2620&tx_sbproductdatabase_pi1[showUid][backPID]=105&cHash=0d01314f22]Beyer style really comfy. The Beyerdynamic T1's give a lush wide soundstage with excellent instrument separation drawing you into the recording, the stereo image being nothing short of 3D. The focus here is in the highly detailed treble and midrange but the bass is warm, deep and well pronounced giving the overall sound superb transparency, weight and authority. Joining the big boys, the T1 must be auditioned alongside Grado's GS1000 and Denon D7000 before you make your ultimate headphone purchase.
