Nutubes return to iBasso Audio, bigger and better through Amp13 for DX300 and DX320. The size and power supply afforded by their flagship music players allowed iBasso to take this tube design to new heights.
That extra circuit board space has allowed Korg's sixth-generation Nutube direct-heated triode to achieve new levels of signal-to-noise ratio, transparency and output power.
Still Headfonics say Amp13 does all the above while offering the liquidity tube lovers desire with an even-harmonic character through single-ended operation. Musicality won out for Audio-Ph. Upgrading to iBasso's mature Nutube tech was totally worth it to Audiophile-Heaven. [See Product Desc. For More]
