The Nobsound NS-08E is a nice little amplifier if you want to dabble in tube sound with your headphones without breaking the bank. It had no problem driving my Focal Clear and Hifiman Sundara headphones when connected directly to my Samsung Galaxy S22 Ultra using a USB C to 3.5mm Audio Aux Jack Cable. There is very little noise with this amp and the sound is rich across the range of frequencies. The documentation shows the amp using 6J3 tubes but I have found little clear writing on the tubes to validate the model but my eyes arent the greatest. I have attached pictures. The documentation also lists a wide variety of tube types that can be used if you want to get your feet wet with tube rolling. The manufacturer documents that the following tube can be substituted: 6J1?6?1??6AK5?6BC5?403A/B?5654?EF95?CV850?6J2?6?2??6AS6?CV2522?CV4011?6J3?6?3??EF94?CV848?6BC6?6AG5? 6J4?6?4?6136?6BX6?6AC7?6AU6?6J5?6?5??CV2521?6F36?6AH6?6AN5?6K4?EF93?6K5?6K4??6BA6?6DA6?5749. The manufacturer also states that this amp can be used as a pre-amplifier. I have never tried this but if you do I would recommend that the volume of this unit is turned way down when connecting to another amp. Then increase the volume on the Nobsound very slowly until you get to your desired listening level. The documented specs for the amp are as follows: Output power: ?1100 mW (32 ohm)Headphone Adapter Impedance: 18-600 ohmTotal harmonic distortion: <0.005%SNR: ?110 dBFrequency Response: 20 Hz - 30 kHzSize: 111*69*32 mm / 4.37*2.72*1.26 in (Height: 73 mm with vacuum tube installed)Net Weight: 185 g / 0.41 lbPower supply: DC 6V / 2000mA This listing includes the amplifier, the two stock tubes and the power supply.
