I think the OP shouldn’t be buying anything else. The Helix will sounds terrific through a pair of $1300 dollar reference IEM’s. I have the helix, and the 64 Audio A6T’s. I run out of the headphone jack and play volume at 1/3 the way up and it sounds like heaven. If you are not getting the same results I suggest you buy a $5 dollar patch from someone who has had the helix for years, or try some impulse responses. Don’t know your music style but the matchless amp sounds fantastic with an impulse response. Don’t buy any more gear, instead spend a small amount of money on impulse responses. I have some from Ownhammer, Livereadysound, and tonejunkies.
