For any audiophile, the amplifier is truly the centre of his hi-fi world. For everything flows into it, and then on to the catalysts of his sound. So if you have invested in a pair of KEF R3 speakers and great audio sources, it’s time to carefully consider the Nobsound 300B Monoblock Vacuum Tube Integrated Amplifier to bring out the true emotions in that Dire Straits album.
The Nobsound 300B has a lot going for it, least of which is a luxurious industrial design aesthetic, which easily sets it apart. Terminator-ish brushed steel tones and knobs make this an easy attraction in your Man Cave or living room.
The Monoblock aspect is one that sets this apart [and rather justifies it’s price tag]. Both the amps have, given their stated goal of reducing crosstalk, an independent power supply and signal ground wire. The multistage CLC filter circuit of the device ensures quieter backgrounds and more intricate details. Nobsound has gone for some premium materials including a Japan Z11 Transformer, Siemens high voltage capacitors, German red WIMA capacitor with good density of sound field, Japan ALPS27 potentiometer, US 24K gold-plated connection terminals and so on.
Interestingly enough, the device comes in three tube versions to choose from, ranging from a Shuguang 300B ×2, Shuguang 6SN7 ×2, Soviet Union 5U4M ×2 to a JJ Tesla 300B ×2, Russia EH 6SN7 ×2, JJ Tesla GZ34 ×2 combination at the higher range of the scale.
This single-Ended Class A amplifier has an 10W×2 output power, 20HZ-30KHZ frequency response, with a 100KΩ input impedance and 98dB Signal to noise ratio.
The Nobsound 300B Monoblock Vacuum Tube Integrated Amplifier is much recommended for the serious audiophile. For as true audiophiles will attest, a good amp will boost your sound, while a great one will supercharge it. The device will retail starting at $699.
