Beautiful! I’m particularly interested in your system as I’m interested in the Super HL5’s and I also probably listen to the dead more than anything else. It seems like you enjoy the combo. I was worried the Harbeths might be too polite for live Dead
Nice. Don't tell Alan Shaw you're using tubes with his speakers - he'll likely tell you to buy any old SS amp, because they all sound the same. Poor Alan, needs to loosen up. Enjoyed my previous Harbeth M30.1's with a little ARC tube amp.
The 40.1's are more natural sounding, full bodied and take you into the emotion of the music. I used a REL Storm sub when I had the SHL5's, but could never get the bass from the sub to properly synchronize with the speakers. The 40.1's don't need a subwoofer and the bass is outstanding. Bass is fuller, midrange much better, highs are less harsh and are smooth as silk. The 40.1's are not everyone's cup of tea, but I like them so much I've owned them twice.
Very nice looking system! I'm intrigued by the Air Tight amp and the Lampi Big 7... both items I've wanted to hear. I've had the SHL5's previously, but not the new "plus" version. If you really want to treat yourself, find a used pair of M-40.1's. They don't come up very often, but they will take your system to the next level.
Even though my system is pretty simple it took a lot of experimenting to get where it is today. Aside from (too much) direct experimentation with new gear, the feedback I got from fellow Agoners was essential. The Air Tight amp is a perfect example of receiving recommendations to try a new component---and having it be a perfect fit.
In looking at your system, I see you're a vinyl guy that has crossed over to the "dark side" with the Atlantic DAC--glad to se you're enjoying it. The Big 7 is my 4th Lampizator DAC and I can say that, for my personal listening tastes, it's truly amazing. I could not give a higher recommendation for their products or customer service.
