iBasso's DX200 AMP5 is a great purchase if you would like a bit more depth, warmth and 'punchiness' compared to the superbly refined and detailed sounding AMP1....provided of course that you don't need balanced connections.
To my ears, it retains ...Read morealmost all the detail, whilst (just very slightly) smoothing the top end, but making it more 'musical' for tracks needing a bit more energy and oomph in the bass.
Thoroughly recommended, but as usual this will depend on your musical taste and synergy with your headphones / iems - maybe not ideal if you already find your 'can's or iems a bit bass heavy with your DX200's AMP1, but otherwise a good choice as it provides an alternative sound character to the AMP1.
In summary, the AMP5 expands the DX200's sound character and is worth considering given that you can easily swap between the amp modules for the best match with different 'cans' or iems you choose to wear, or when listening to different musical genres.
