Universal Audio Apollo X4 Gen2 AC

Sound quality has been improved compared to previous models, no complaints about that area. Headphone amp has also been improved but it's still not at same quality level with other parts of this interface. Easily replaced with outboard unit so it's not a big deal. After few months use still no regrets about this purchase. I'm not big fan of UAD plugins but even without those this interface is worth to consider.

I replaced an older rackmount Apollo Quad with this interface for home use. For this purpose it is much more convenient to have it in desktop form. The converters are significantly better and I am very happy to have monitor correction built in.
