Firestone are beginning to take the higher end audio game very seriously nowadays and the new HDB+ shows just how the company are willing to listen to what the community has to say. They got rid of the recessed sockets and some other niggles that we had about the previous HDB and they now have a truly wonderful portable amp that is both a joy to both use and own. Build quality is nothing short of stellar; the design beautiful/classy and the the sound is right up there with the best of other top of the line amps from other companies whilst even throwing in the ability to go balanced at a great price. It does exactly what a portable amp should do which is amplify the signal cleanly providing oodles of power for harder to drive cans and compensating for DAP amp deficiencies it is very very hard to fault this at all.
As a complete package I can’t think of something else I would rather have whilst on the go and as such my own personal rig will now be a combination of the HDB+ in conjunction with the Ibasso DX50 and Minerva Mi-Artist pro. I guess that means we all kind of like it here. Happy listening.
