I adamantly believe that modern day amplifiers which are operating w/in their design limits that are indistinguishable from one another in terms of sound quality. To read more on this proposition, see this fairly exhaustive discussion If you're persuaded by this then you'll find any integrated or AVR would suffice provided it can drive your speakers loudly enough without distorting (an easy feat w/ Klipsch's b/c of their efficiency). That said I'm going to recommend that you chose an Integrated which has both Tone Controls AND a Mono switch.
I recommend tone controls because very few recordings are perfect. In fact, there are some wonderful songs which were rendered nearly unlistenable by poor micing, bad venue acoustics, or bad mixing, etc.. In such cases, a simple adjustment of the treble control can make this song enjoyable. Some will say such tampering basically undermines what the artist wanted you to hear but I say BS: if the song goes from "unlistenable" to "enjoyable", I'm quite sure the artist would strongly approve.
I suggest that a Mono switch is equally indispensable. Do you listen to any music from the 40's - 60's?? During the early days of Stereo some songs had some very strange mixing. Instead of using stereo to replicate a soundstage where each instrument and voice is placed somewhere b/w two mics some treated it like a special effects opportunity. For example, some early Beatles songs had Vocals coming completely out of one channel and the music out of the other. To me, these otherwise fantastic songs are almost too goofy to listen to. The problem is exacerbated if your sitting closer to one of the speakers.
Depends how much work you want to put into it and what your resulting finish requirements are.
If you want a smooth finish, go with the epoxy though may take a few coats. Rough one coat, duratex.
The speakers look fine and someone else will surely find them beautiful I do realize that a lot of these were sold so there are a lot of people who like them just fine. People bought Avocado appliances also. Its just an opinion and not the end of the world. We don't all have to agree or pretend to all like the same things just to try and make everybody happy (because that never happens). We all cannot like the same things, there is no insult intended. I was trying to point out that they are not a raw Birch finish. I just happen to find this sort of finish a shame. That's just me. Please feel free to ignore if my opinion conflicts. My opinion or anyone else's opinion for that matter is not going to change the opinion of anybody. This is like ice cream you either like the flavor or you don't. No one can make you like something that you don't or make you not like something that you do. Why has having a difference in opinion become a bad thing?
Welcome to the forum.
If you look at my gear list below, you will see I like things to match, both visually and audibly. With that said, my first choice would be the the Marantz.
Maybe look at the Yamaha A-S2000 or A-S1100.
I am sure you have your reasons but my experience with these brands has been wonderful.
It's still coming across fairly critical Moray to a guy trying to sell a speaker.
I use a smiley face because I know your heart is pure and you have such a wonderful passion and expectation about how the finish on speakers should be.
I'm not being critical of your post, I just see the La Scala's a bit differently. I think they will clean up nicely and I like a satin polyethylene finish whereas you stated a fondness for the high gloss finish, probably in lacquer because you are an old school guy.
Nothing wrong with that either, either way it's just personal preference.
please don't take my comments on the terrible finish as an indictment of the loudspeaker. It does not matter if the factory did that finish or some guy who lived next door who said he knew all about finishing furniture did it, it is still a terrible thing to do to a nice piece of birch.
I know it's laying down I don't know how to rotate it but here is some well aged raw birch with a coat of urethane or similar such varnish along with 25 or 30 years of natural patina. You don't ever get to see this if you (or the factory) slop walnut oil wiping stain all over your birch veneer on day one. I like the speaker but I feel a deep loss for the finish that might have been.
I've been following your thread on avsforum.com DIY Speakers and Subs.
You have over 100 comments and 3,000 views. It's by far the hottest topic posted in the last month, probably in 2018. There are a lot of guys over there commenting and making suggestions. You have gotten some of the top DIY sub guys interested in your project.
Building a sub with a 32" driver is instantly over my head, making me one of the viewers, not one of the commenters. I will be following to see how things progress.
