In the vast and diverse world of audio, music enthusiasts are constantly seeking a pure and authentic sound experience. It is in this quest for acoustic excellence that the Puresound A30-R integrated tube amplifier was designed. Created to deliver unparalleled performance at an affordable price, the Puresound A30-R embodies the very essence of Class A amplification.
The Puresound A30-R amplifier is built on a solid base architecture, implementing push-pull configured output pentodes biased in Class A. This approach ensures minimal distortion and a natural, relaxing sound that will captivate even the most discerning audiophiles. However, what truly sets the Puresound A30-R apart is its continuous innovation and subtle improvements for an even richer sound experience.
In a constant quest for improvement, Puresound has opted for a major upgrade to the power supply. Instead of a single power transformer, the A30-R now incorporates two separate transformers. One for the rectified valve HT supply and one for the filaments. This modification results in cooler operation and reduced background noise, thus enhancing musical immersion.
The output transformer design has been carefully refined, involving an improved lamination material and a different winding arrangement. These subtle improvements translate into a wider bandwidth, delivering exceptional sound reproduction and uncompromising clarity.
The Puresound A30-R offers remarkable versatility of use. With the ability to select up to four different source components, this amplifier gives you total control over your audio experience. Volume control, managed by a high-quality ALPS Blue Velvet potentiometer, ensures precise and smooth management of sound intensity, adapting to your musical preferences.
The Puresound A30-R amplifier is designed with a commitment to excellence. The robust and reliable Electro Harmonix 6550 output tubes power an Ultra Linear Push Pull configuration. This combination delivers exceptional power and sonic clarity, bringing your music to life with unmatched depth.
Carefully selected components, such as carbon film resistors and SCR polypropylene capacitors, ensure consistent and reliable performance. Additionally, the Auto Bias system eliminates the need to readjust the output valves, simplifying maintenance and ensuring optimal performance.
With the ability to configure the output for 4 or 8 ohm speakers, the Puresound A30-R adapts to your preferences and audio system. Furthermore, the output stage can be switched to a triode-coupled configuration, further linearizing the operation of the valves, ideal for higher sensitivity speakers.
