I feel that the sound has been consistent the last week or so…so much that I stopped evaluating the Arcam and have been able to just enjoy the music. It was really bugging me initially though on how the overall sound had changed with a reboot of the same Firmware. I had rebooted a couple more times since the last time I posted here. One of the reboots didn’t fully go thru, did not complete, and when I played the amp after that one it sounded bad again. So I had to force another reboot, it completed, sounded like what I guess is how the amp should sound and I haven’t messed with it since.
I don’t know what to make of it, I don’t know if I should be concerned with it. Maybe I didn’t do something right the first time I Firmwared, but it did complete and the upgraded version was installed when I checked the Menu Net info. I strongly felt it sounded flat, kinda lifeless but very clear and powerful. It’s definitely more dynamic and exciting now, although I do have to turn up the dial more than initially. First it was loud around 19-20, now it’s more to 30. I also feel it sounds slightly different when I go past 40 on the dial. But anything over 40 isn’t really where I normally listen anyway.
So yeah I have some concerns about Firmware’s and how they effect the amp. I guess I’m just not use to that though, I’ve never had an amp or receiver that took updates…I’m use to an amp having a sound and that’s it, it is what it is. But maybe the updates have more to do with the dac/streamer/HDMI/ digital stuff. I just recently started using an analog input, so I can’t compare that to the initial sound I was getting thru the streamer. Even with these concerns I’m still using it, because it does sound good lol. To me it has the clarity and punch of a good Hypex Class D amp, but with better smoothness, more extended treble frequency’s, not as dry. The Class G does sound different to me than other amps, but it’s not really a bad thing.
I don’t know how long you’ve had your unit, and normally I’m not a big endorser of “everything needs to burn in” but it seems this amp gets better. I use to be in the camp of people that thought our brains just get use to it and that’s why we think it sounds better, but one thing that can’t explain is when soundstage gets better. That is one thing I feel my Arcam is lacking…the depth of soundstage. I felt it was literally non-existent, but now the drummers have slightly, just slightly, moved back a little. I’m hoping Dirac will fix my depth of soundstage issue.
And yeah I still haven’t run my Dirac, I’ve had my boom mic for 2 weeks now. My daughter had been home the last 2 weeks with COVID though and I really wanted to run the amp in and get a feel for it before Dirac. I need to get on it though, I think I have a month left before my 60 day return policy is up. I’m thinking I’m going to keep it, although at this point I just want the amp inside of it lol. I put the Arcam in processer mode and hooked a tube preamp to it. The Tubes paired well with the Class G amp in my opinion.
Sorry I babbled on so much, but there is more I could say I’m sure lol. This is a big purchase/big decision for me, I don’t normally buy integrated amplifiers, so I’m stuck with everything about it, and I’m going to want it to last many years. That said the Arcam has all the features one really needs.
Please let me know how it’s working out for you, if the sound changes on you, what you’ve noticed and your concerns. I’m definitely interested in your thoughts and any issues you are having. Good luck Paul.
