I kind of agree with Gano on the amps looks and connectivity. It looks good in real life but minimalist. I would have preferred a different array of connectivity. Made a modular compartment for Phono stage if anything, keeping it an RCA input. I like the SQ but its being evaluated currently on lower end mid gear, depending on how one sees it.
I always felt the Hegel was overkill but on 807Ws it did well, but its an easy speaker to drive. The Keces, Hegel and seemingly the CA-1 never seems lifeless like the typical brands I previously had could. I had a HK 3490 years ago and in the daytime, could sound kind of flat, like dullish but livened up at night time listening when are ears hear differently, that I believe can be explained scientifically.
So far, I feel the Ca-1 fits between the Keces and Hegel, closer to the Hegel. The Hegel designed in Norway but built in China, I do not think we saved anything as Hegel charges as much as possible to keep the marketing chain and their business healthy. It's markup. Not going to say it would be double if built in Norway. If that were the case it couldn't compete.
The CA-1 to me isn't a giant killer but a good sounding articulate performer. It won't be everyone's preferred choice. If you want a smooth. relaxed presentation look elsewhere. If you want excitement and transparency, comparatively speaking it could be a good choice. Especially if you add a dac and only listen to movies and CDs. Simple and yes, it sounds good. I'm sure it could compete with more expensive gear in certain cases and with certain gear. Don't know how it measures and I just went back and forth with Nemo regarding the Totem Bisons between the reviews and how it measured, trying to figure out how it sounds and whether it could be paired with this amp. That didn't resolve any concerns but I look at measurements to at least come up with some data for expectation. He doesn't. But his gear isn't my gear and his room isn''t my room. Same for ears and preferences.
Seemingly, the little Keces may not be powerful enough for Totems and I wanted to find a replacement for the Hegel as its 40lbs...I want something capable but lighter.
Some have stated that they had gear costing thousands and when they heard the CA-1 it impressed them. As an amplifier is designed to amplify, why don't they essentially sound the same? Probably due to build and component quality for SNR, distortion, power on demand output, etc., and they do have different flavors.
If it does sound better or at least as good as more expensive gear then I am done. Seems like reliability is good and should last for most of my life, what remains. So, 20 years perhaps? Also, I am hesitant to buy really expensive gear as my needs in SPLs wouldn't utilize what i paying for, in amps, speakers, etc. Sure, there are pieces I would like to have and if used at an affordable price I might jump.
But in the 1000 to $2000 price category, there's alot of choices out there, new or used. I think this amp competes, for whatever that's worth.
I think the CA-1 is a solid, albeit simple performer. Given that, I do wish it were a bit smaller, say a few inches less wide. Other than that and my connectivity preferences, it's good, especially for what I paid. Say a higher end sounding but still (audiophile) "budget" amp which if it ever needs service seems simple enough to have worked on, hopefully.
And kind of neat to have a US made Van Alstine in the system.
