Warranty

Check with the manufacturer for details.

For Quebec residents: See the Availability Guarantee disclosure in the Specifications section below.

M4 audiophile Class A preamplifier, guaranteed quiet installation, warm and tube-like sound, excellent resolution, rich and sweet mid-high frequencies, and deep and powerful low frequencies.

TL431 high-precision voltage regulator ensures balanced and accurate op-amp power supply, constant current, and many advantages over common three-terminal regulators.

It should be noted that Class A regulated power supplies generate some heat; this is an inherent characteristic of the circuitry, and you can use it with confidence.

Simply connect the power and signal cables after receiving the product.

The heat sink has been changed to two large integrated heat sinks, several filter capacitors have been added, a balance adjustment has been added, the amplification factor conversion has been implemented, and a 58AG92M warm-sound dual-precision op-amp with a gold-plated socket has been installed.
