Hi, all -
Reviving this thread with an update. After stalking HifiShark for a few weeks and continuing my self-education on affordable options, I took a left turn and bought a gently-used Peachtree Nova 220se. I thought it would be a good opportunity to learn whether Class D worked for me while driving our current Mini Walshes and waiting for the new Walsh 2000s to be shipped.
Why the Nova? I was intrigued by IcePower, wanted to see for myself whether the preamp tube would soften the rough edges of Spotify streaming or was just a pretty blue glow on the faceplate, it had a headphone amp (not available with BelCanto/Nuprime), and the price made me less worried about making a mistake.
First impressions? Positive. It's too early to dig deep, but...compared to the Marantz PM 8004...
Bass control and definition is notably better. I didn't know the MiniWalshes had this much in them - and if I had changed amps before committing to the new 2000s, I might be satisfied with the Minis. It's noticeable even on clean-source streaming, and at relatively low volume. My better half noticed this within minutes.
Complex musical passages are sorted and you can trace phrasing more clearly, also at low volumes....for example, those of you who know Steely Dan's pristine 80s recordings, the title track to Aja has some complex melodic and counterpoint threads that can get congested. The Nova did a great job parsing them while remaining musical and pleasing.
I was surprised by how the Nova handled jazz and female vocals, as well. This was one of the things I was most apprehensive about in Class D amplification. But Diana Krall and Patricia Barber vocals were smooth while background instruments were clean and clear, especially bass. Not fatiguing, just musical. After listening analytically, I was able to just relax and get into the music.
I'm listening to Spotify as I write this, and I realize that I am enjoying the stream without wincing at the compression and muffling that I had become used to. It's still not as open as even redbook, but it is better - expect that may be the Peachtree DAC. I can tell which selections on the Laurel Canyon stream were better mastered more easily than with the Marantz.
It's too soon to tell whether my reactions are simply from hearing 220/350W vs 70/100W, whether the tube makes a difference with streaming, whether Class D will be more fatiguing or less natural as I listen to more of my most familiar music, and I still can't decide whether highs are more or less open and extended. But it's a really good start.
Did any of you have this type of surprise in moving from Class A/B to Class D? Is it just the way that Ohms respond to power? Would like ot hear your stories, too! I'll post a little more after some more listening.
