Today is blind test day for the signal sense auto turn on/off feature of the 1200AS. I'll let you guys know if it's completely transparent or not. If so when the amp is in standby, to turn on or off simply play music, or stop playing music. If you want to keep the amp warm full time for best sonics right away, just keep the amp on.

Okay I’m going to offer the Furutech DPS-4 internal power cable as an $100 upgrade option for the SE.

I just sent you an email too Mike. I think the the Furutech DPS-4 internal power cable will make a significant improvement to the sound of the SE, thanks for offering this!

Lot's of upgrades for the dPS-4 coming in so far. I'll invoice you guys next weekend. For the ultimate external cable with the internal DPS-4 option look no further:

Thanks to Don and Jay also for bringing up the suggestion to try the DPS-4.

I forgot to tell you guys. The standby operation with the touch switch works flawless. Touch the button and the music just gently fades out. Touch again and it gently fades in. No pops or anything like that. Very smooth operation. I’m very happy Barrows suggested this and I decided to implement it. Also no more mains switch in the power path.

Thanks Mike! :green:

The DPS is a good cable but I only sell it with NCF plugs. IMO, you're better off with the S55N and NCF plugs rather then the DPS with lesser plugs. So a DPS PC is about the same price as the amp!  :o

OTOH, the DPS is a lot less expensive vs other top cable brand's high-end PCs and will beat a vast majority of them.

Well if one orders the DPS-4 option on the SE, they’ll have both the best cable and NCF inlet. So they’ll be in great shape for either option from you.

The deadline for Lot 1-5 DPS-4 upgrades will be Feb 18th at 12pm Pacific time. Following that I’ll send all invoices.

Mike,

Is there a discernible SQ improvement with DPS-4 inside mated to S55N PC outside vs. S55N inside and outside? [Given the prices for the DPS-4 PC, I suspect I'll draw the line at S55N PC. Though, I will consider upgrading to DPS-4 inside.]

Thanks.

Michael

Jay and Don both think so. I’m over at Jay’s listening now and sounds incredible. So far our listening tests have confirmed that the cable on the inside of the case matters just like it does on the outside.

Well we have spent lots of time now evaluating the signal sense feature on the amp. None of us are able to hear any difference whatsoever between it connected and not. We put on some tracks with a very deep soundstage, and instruments located in exact spots on the stage. Swapped over to input connectors with the signal sense wire in place and exactly the same. So looks like the Icepower engineers did a good job. I will offer this feature as an option.

I installed a Synergistic Research Black in my amp. They said that the fuse was directional and to try both ways, they were right. So Mike when you test fuses try them in both directions. The amp just keeps sounding better.

Would you, Jay, and Don be able to describe in what ways the DPS-4 sounds superior to the S55N cable?  I personally would find it helpful to read something more than “it’s better.”

They want to let the cable fully burn in then we will do blind tests with subjective impressions. Jay said after 2 weeks the S55N changed a lot. But they both noticed an improvement instantly with the DPS-4. And still not burned in.
