Picked myself up a Kenwood KS-5700 today and just thought i'd give my opinion on it incase any of you might be thinking about getting one yourself. First of all, i do not use it just to power my AKG AK240s, i have a pair of Polk Rti A3s on the way which will be the main thing the KA will power. But seeing as how i do not have the speakers yet, its going to spend about a week simply as a headphone amp.
After listing to a a few albums (The Fray's How to Save a Life, Notorious BIG's Ready to Die Remastered, Pink Floyd's The Dark Side of the Moon), i find i really like the signature of the KA. It's quite warm, but still is detailed and layered. Lows are very warm/smooth, not to overbearing. Mids are excellent, they are sooooo warm and have a certain life to them. Highs are nice, not harsh, just a tad on the bright side, if that.
The one gripe i have with the KA is that i wish it had a bit larger of a soundstage. Thats not to say it has none, i just prefer mine to be very, almost comically, wide. The KA does provide an accurate soundstage however, just not as wide as i'd prefer.
Cannot wait to get my Polks here so i can hear how they sound. I'll post an update once i get them in and give it a solid listening session. Shoot me any questions you have on it, i'm here to answer.
