• Multiple Inputs
• Stunning Sound
• Integrated Power Supply

The star has been born again and the successor of the famous HA-2SE amplifier is ready for the market to rise even higher than its predecessor. The HA-2SE was one of the best-selling devices from the Auris product range which launched Auris Audio to the very top of the world when it comes to the headphone amplifiers. After many years of “flow”, the Company stopped producing this particular amp in the end of 2019.

The HA-2SE gets its successor that will have similar basis and price range but with a lot of improvements and additions compared to its predecessor. As the main feature, it is adorned with a balanced input and output.

Amplifier

Auris HA-2SE + is a balanced single-ended headphone amplifier. The lineup of tubes is classic Auris, with the use of four 7-pin Ei PL95 pentode power NOS (new old stock) tubes, which are the equivalent to 6DL5, and a single ECC81 dual-triode input tube, also known like 12AT7.

Transformers are the essence of quality, and therefore products of Auris Audio contain only manually wound transformers on a double C core produced by Auris Audio. Every single transformer is manufactured in compliance with strictly defined requirements, thus providing almost a linear characteristic in the whole acoustic/sound range.

Design

On the front panel, from left to right, you have the On/Off Switch, Input Line Selector, and 4-pin XLR balanced output. In the middle is the main Volume Control Knob and right next to it is the 6.3 mm single ended headphone output. On the right side is the Headphone Inpedance Selctor at 50/150/300/600 Ohm.

On the top of the unit you have the five tubes (4 x PL95 and 1 x ECC81) that are centered on the design and they’re protected with a little grill, separating them from the controls.

On the back of the unit from left to right you can find the XLR and two RCA inputs, as well the Pre Output. In the middle is the Tube EL 95 or PL 95 switch. On the right side us the Input Voltage Selector, Power Cord Inlet and the On/Off Switch.

Impendance Selector

o make your headphones shine at their best, we designed the HA-2SE+ with an impedance switch, which allows you to select 50/150/300/600 Ohm according to the type of your headphones.

Tubes

Vacuum tubes used in Auris Audio products are subject to individual testing and internal inspection, so that only selected and match-paired tubes of the best features are incorporated in our products.

The Auris HA2-SE of course is a tube amp and it uses four PL95 or EL95 power tubes together with an ECC81 input tube. The EL and PL95 tubes can both be used in the amplifier and you only have to flick the switch on the back as these tubes have different heater ratings.
