There is no problem with my Hegel H590 or Class D Audio SDS 470C amps, just my ARC Ref 150se. So... it's not the room... its the amp.You might know that I'm a tube amp manufacturer (that also holds a patent in class D amps as well). Take it from me on this bit (since the solid state amp is fine, we'll assume that a DBA isn't needed): speaker cables can affect tube amps a lot more than they affect solid state! So I have two recommendations: try several different cables and keep the cables as short as you can: under 3 feet if possible, and make sure the connections are tight. I would also try different taps on the output transformers of the amp as that affects things too- sometimes counter to what you might expect.

Yes... Ralph... I will try some of your suggestions. I have your M60's and have talked with you about upgrades - though, I think mine have the 3.3. upgrades. I'll try the 16 ohm taps and maybe the 4 ohm taps to see if that makes a difference with the ARC 150se's. And I'm using Paul's cables, and have his Zeroformers, which I got for your M60's for my Maggies. But, as you know... the M30.1's and M40.2's have a bit of an emphasis in upper bass / lower mids, which I resolved with some good SS amps (the ones recommended by Harbeth)... but... I think I may prefer the sound of the ARC 150se, except for the bass bloat that is not there with the SS amps. |
Roon has the ability to run DSP through the output. By all accounts this works very well, and at the price that Roon is, it is a very cost-effective solution. Of course that won't solve vinyl issues. And with CD would require the ripping and storing of the music. But if you do play your music from a digital source and just want dsp with no pre-amp or dac then this would be the best solution. |
