Kingrex T20U Tripath Amplifier Usb/Dac

Considering the price of this beautifully designed and machined DAC/Amp, you'd be mad to buy a soundcard for your computer. Initially, just add a £1.99 USB lead and speakers for a musical experience so much more satisfying than a PCI card and the boom-tizz sat/sub monstrosities that have too long blighted our desktops.

Measuring about the size of a hardback book, this lovingly crafted and compact convergent device delivers mellifluous musicality even in its 'base' specification, with a sound quality more akin to classic tube amplifiers than shrill transistors. However, to hear what it's really capable of, the first substantial upgrade to consider is the KingRex PSU which adds weight and authority to the bottom end and dramatically enlarges the soundstage, without compromising any of its delicacy of touch. A similar step up in terms of dynamics and resolution is afforded by adding one of the matching preamps.

All the components used in T20 & T20U are of the highest quality and have been selected through intensive listening sessions – from the PCB itself to the high quality chassis and anodized gold RCA and SP terminals.

Introduction of linear power supply
The linear power supply is a better choice for audiophiles. It has less noise and distortion than the switching power adaptor, however, during the AC to DC conversion and rectification process; there is a still minute amount of unavoidable noise and distortion. That’s because the AC power is required to traverse significant circuitry such as transformer, diodes, voltage regulators, and other components.

Specially designed for T20 and T20U, this optional power supply unit features a 48VA toroidal transformer coupled to a full-fledged regulatory circuit with eight audio grade NCC aluminum electrolytic capacitors: 5 x 2,200 µF @ AC input stage and 3 x 4,700 µF at DC output stage. The PSU provides abundant reserve to meet the demand when low frequency transients draw on high-current voltage.
To quote 6moons again: “When the PSUs were added to the pot, musicality thickened. There was more warm air filling up a more expansive soundstage. Bass got deeper, the midrange turned proportionally more pronounced to make the overall harmonics even richer.”

Smls Sa98e

SA-98E is which takes TDA7498E of STMicroelectronics as the core, using Panasonic ( Japanese Panasonic )• EPCOS• PHILIPS ( German Siemens ( Holland ), ALPS ( Philips ) Japan Alps ), WIMA ( German Weimaraner )• RIFA •ERO senior of fever parts refining ,high quality digital power amplifier.

TDA7498E is the BTL output circuit for class D audio amplifier chip, with strong output short circuit and over temperature overload protection. Efficiency as high as 90%, so it will not generate too much heat in the large power, very suitable for using in long time work ( supermarkets and other public places ). With the double wooden Sanlin avant-garde design and rich colors, this uint is more easy to match your home environment.
Use the power adapter for DC32V SA-98E. Pick6Ω80W power ( THD = 10% ), then 4Ω100W power ( THD = 12% ), power amplifier distortion is with the power increase and increase. So we mark ideal listening to 120W/ power per channel.
