Forums - Question of SE84UFO25 with Volume Control

sz66panzer Verified Member Offline Posts: 9	Question of SE84UFO25 with Volume Control 06/14/21 at 13:25:18 Hi! I'm new here and havn't got a Decware engine yet. I read that SE84UFO25 could choose to have Volume Control or not. My question is that if choose to have Volume Control ,could this SE84UFO25 be paired with a Preamp ,such as paired with Decware's own Preamp? Thanks in advance!

I chose to go with the "Smooth Action Volume Controls" on mine. I have the "20 Position Stepped Volume Control" on my CSP3. I have found this combination to be very versatile.

I have found that infinite adjustability of the SA controls gives me just that bit of volume adjustability that from time to time is nice to have. When I sent my CSP3 in for the Anniversary mods the UFO25 became an integrated and I still had music. In case your wondering... although it was very good (understatement) as an integrated, I would not give up my CSP3-A!

The system is SO good that I don't even give the choices I have made a second thought.

Steve must have set the output of my amp at 75-90% (I am not sure) of its full volume, and I am very happy with the simplicity...

Pal, I question the logic of putting the amp at 100%. I do the opposite. I push as many volts into the amp as I can and use no more that 1/4 of the amp's volume control. I do this for weight/density. I presume you've tried this? You may not be able to push as much voltage since I see you aren't using a CSP3 like I am. Maybe this makes a difference?

I also thought that was how Steve was running his.

"riding the gain" The ZSTAGE manual has a detailed explanation in it.

Well I thought I’d just head down to my room and give it a whirl. Then I remembered that I am tri-amping and I’ll need to tweak all three amps. So I just sat down and started listening to music. I’m curious though and will give it a shot some time when I have the patience.

I listened to all rips today versus streaming and I forgot how much better the rips are. I also realized how much better my system sounds than it did back when last I listened to rips.

__Jon__ Verified Member Offline Posts: 40	Re: Question of SE84UFO25 with Volume Control Reply #10 - 12/20/21 at 21:21:05 I wonder if Steve would consider a different stepped volume control, with 40 or 50 steps, as a custom option? I have the stepped on my ZMA and like it, but the volume changes are substantial between stops. If I didn’t have finer control on my DAC, I might feel differently.
