Advice for integrated amps


I am looking for opinions of the krell kav300i, plinius 8150i, and the manley stingray integrated amplifiers. I have heard the krell but not the other two. Also, if there are any opinions about the audio research ca50. thanks.

Hi. I auditioned both the Krell integrated and the Classe CAP-151 integrated at home. I was disappointed with the Krell: sound and soundstage TOO FORWARD (in your face),volume level TOO TIGHT (even minor adjustments in volume too, too loud), and a disappointing upper end. I will say this about the Krell: really good upper and lower bass response. The Krell is great if you listen to rock. Forget it if you like classical or jazz. The Krell is not bad, it's just disappointing - and too expensive for what you're getting. Now, the Classe CAP-151: Good bass (not as good as the Krell, but still very good). VERY musical midrange: not perfect but...well, musical! Sweet upper range. Good for classical and jazz, but should be ok for rock (remember: 150 watts/channel will definitely pump out volume and bass). Best news: the Classe is built like a tank - heavy, solid, well constructed. And because it's made in Canada, you're getting more bang for the buck due to the very favorable exchange rate. It's $600 or $700 cheaper than the Krell. The Classe is designed so you can shut off the built in pre-amp section (with a push button) and connect a separate pre-amp if you decide to upgrade your system later.
I suggest you listen to the Jeff Rowland Concentra Integrated amp. Very musical, etc. I have one and like it very much.
I heard the Krell and agree with the assessments above - not nearly as good as the price would require. I owned a Classe CAP 100 - good sound, comparable to the Krell for a lot less scratch. I have since bought the Pathos Twin Towers and am in heaven - clarity, smoothness, detail, extension. If you can live with the heat a Class A amp puts out (it runs really warm) and have 8 ohm speakers which can live with 30 watts, it is an amazing piece. There is a used one on Audiogon for $3500 (comparable to the Krell) and would definitely look into it.
