The HL5 has more bass than the 30, but the cabinet is bigger so no surprise there. The 30 tweeter, while initially sounding a bit laid back, is really quite refined. Definitely a big step up from 7ES. I'd probably take the 30s myself, though if running w/o a Sub, the HL5s are probably the better choice. Either are really musical and have a lot to offer, with sound that belies their (humble) looks.
