Okay so, these lascala Industrials are going nowhere, at least for the time being even though they're huge and taking up way too much space in my room . if anybody that hasn't yet but gets the opportunity to listen to these with the right amplifier even with the so-called dreaded Al crossover please do so. A while back I was asking for opinions on what amp to pair with this particular speaker with this particular crossover as I had limited options availability and budget, so 3 amps later I can honestly tell you in my opinion that this Soundstream da1 amp with this particular set of speakers kicks ***. I love the Sunfire 300 but not with the lascala Industrials, it kicks *** on the klf 30s though. I also tried the Adcom 555 ll with the lascala Industrials but again was lacking clarity, there was a lot of distortion in certain ranges which literally hurt my ears. So last but definitely not least I hooked up the Soundstream da1 and excuse my French but I ******* love it it's been about 2 weeks, just sounds better the more I listen to them with this particular amp. I don't have a whole lot of experience with this, but I certainly highly recommend this particular amp with this particular set of speakers. I honestly believe I found a rare and Hidden Gem in this amp. Again I as many folks on these forms are not familiar with this particular amp but I am so happy I lucked in 2 it. As we all know the Adcom ain't no joke but right now it's taking second stage to the Soundstream and will be used as a backup in case something does happen to the DA one
