Heard the New Jeff Rowland 302 Power Amp?

Yes, it's the best amp - by far - that I've ever heard. You say you're looking for something warmer sounding, but don't specify what you would be comparing it too. I see that you have a Pass X-250 and don't know that amp. I CAN tell you that the 302 will not be warmer than the X-150 or X-350. Feel free to e-mail me if you want to discuss further.

I am listening to a 304. This is the best yet from Rowland. E-mail if you wish to discuss.

The comments by Jfz confirm what the Stereotimes reviewer said about the 302: that it actually has more top-end energy than a Pass X-600 (thus it may sound brighter than Pass), and that it has a somewhat lean presentation compared to previous Rowland designs. Thus anyone looking for warmth or a classic Rowland sound may want to approach the 302 with caution. A serious home audition would be in order here. While I haven't heard the 302, I find Pass X amps lacking in warmth (I once owned the X-250), while earlier Rowlands can be warm & musical although they are not the most revealing amps.

I have heard the Rowland 302 with a Wadia front end, Cardas cables, and on Avalon Eidolon Diamonds. I have also heard the same system with a BAT VK - 150SE, Levinson 335 and 336, and Classe' CA 400. The Rowland 302 BY FAR mathces the perfect balance of detail, transparency, musicality and warmth, and ambient retrieval. It is very musical and warm, but more detailed than the Levinson! In fact, I thought it was more musical and tube like than the BAT gear. The 302 is a great amp, a new benchmark in my opinion.
