Sorry for not updating this thread last weekend. I've been very busy with work.
I have also been continuing my speaker break-in. I have about 160 hours on the setup. I still haven't seen the wild swings in performance that others have noted. I can say that bass response in the Max Hemps has tightened up considerably and is much more satisfying now. I have even taken to doing some listening without the DeepHemp sub in the mix. I undoubtedly still prefer the combo, and that shouldn't really surprise anyone. But I can also see for the first time that the MaxHemps are capable of standing alone quite nicely.
As for the stridency...it is beginning to smooth out some. But it's still there and I can hear it, though to a lesser extent. I think overall things are on the right track. The mids still seem to be pretty much right where I found them out of the box: spectacular.
I have been very careful to listen to a wide variety of music. Here is a sampling of what I have been listening to, spread out over the past 10 days or so. All of it is vinyl unless expressly stated otherwise:
Al Smith - Hear My Blues
There probably aren't too many people here who have even heard of Al Smith. That's a real shame. Originally appearing on Prestige in 1959, Hear My Blues was recently reissued on vinyl by OJC. Five months ago I was buying up hard bop jazz vinyl reissues like crazy. This one is a real gem, and Al Smith has the right kind of swagger to fit the mid tempo blues numbers and ballads that grace this record. If you like blues and jazz then spring for the record while it's still available. I snagged it for a measly ten bucks and it was worth every penny. I wish I could say the sound of this record knocked my socks off, but I listened to it right after I got back from my business trip when the speaker setup had about 40 hours on it. The highs and even the upper end of Smiths vocal range still had a harshness to it that bothered me. I listened to the album from beginning to end, but it wasn't an easy listen on these speakers despite the passionate performance by Smith. The MaxHemps obviously needed more break-in. No surprise there.
Bachman-Turner Overdrive - Not Fragile
A criminally underrated hard rock staple of my high school years. The problem with the album is that the song "You Ain't Seen Nothin' Yet" got all the radio air play. It's a great song mind you, but it misled people hungering for hard rock into thinking that Not Fragile was really pop oriented. The thing is that this album rocks pretty damn hard, and the title track that leads off side one is a perfect example of what the record is really all about. If you have a vinyl setup then buy a copy if you don't already have it. If not then good luck finding a CD release that's not mastered hot. I bought my copy on eBay for $6.00 and it played perfectly, no pops and no clicks. It also sounded pretty incredbile on my speakers. This is thunderous stuff, and the DeepHemp was hammering out the rythym while the MaxHemps were gettin' it done on Bachman's stadium sized guitar riffs. I have found hard rock perfection and I like what I'm hearing.
Sonny Rollins - Saxophone Colossus
You're not really a hard bop fan unless you have this record in your library. I have a 180g reissue and it sounds awe inspiring. It also sounded inspirational on my MaxHemps. Rollins was firing on all cylinders on this outing, and it also helps when you have Max Roach taking care of precussion. Easily in my top 100 albums (of any genre), this was a surprisingly smooth listen from beginning to end, and was the first hint that some of the harshness I have been hearing was starting to even out. Good things come to those who wait!
Supertramp - Breakfast in America
I have to admit that when this record came out in 1979...I despised it, and I despised Supertramp. I was a hard rocker and metal head back then. I was on a steady diet of Led Zeppelin, Black Sabbath, and Kiss. Supertramp was for wimps. Well, that's the sort of nonsense that was running through my head in 1979. I'm 48 years old now, and my taste in music has broadened tremendously since my youth (lucky me). Breakfast in America has become a favorite album of mine, and I have it on a Simply Vinyl 180g virgin vinyl pressing. Very low noise floor and incredible sound. This album really opened up on my speakers and it was a thoroughly satisfying listen on all fronts. I would love to have a copy of the MFSL reissue to compare it to the Simply Vinyl pressing.
Bruce Hornsby and the Range - The Way It Is
This was another terrific eBay find. The record wasn't sealed, but didn't have a mark or sleve scuff anywhere and it was perfect when I played it. Easily worth the $7 I paid for it. This was also the first album that I listened to that really told me I truely had something special in the MaxHemp/DeepHemp combo. I was totally immersed in the music on this wonderful record. To me, that is the mark of a really great system: one that allows you to focus entirely on the music and not the gear. This album was that for me.
Santana - Santana
This came in the mail today. It is the Mobile Fidelity 200g vinyl reissue struck from the original master tapes. Yes, at $29 it is a little pricey, but not nearly as pricey as it will get when the limited run is finished and the title is OOP. Man was I in heaven today listening to this record over lunch (one of the benefits of working in a home office). Again, the MaxHemp/DeepHemp combo really did this recording justice, and I can't imagine it sounding better on another setup.
Summary
Things have improved considerably, especially in the bass response of the MaxHemps. There is still a touch of harshness that I'm sure will work its way out of the sound over time. The speakers have smoothed out over the last 100 hours of break-in, and I expect that trend to continue. I have noticed no wild swings in performance so far, and I think I have listened to enough variety in my selections that if something were afoot there then I would have noticed it. I was happy with the way things were progressing when I started this thread and I am just as happy today. I'll update the thread in several days time and let everyone know how it's going. So far, I'm getting on just fine with my speakers.
