…and my TT2 is back from service with a new board! All is right with the world…works perfectly

It is still worrying, the considerable amount of TT2 that go to technical service

I agree though I suspect it relates more to a bad batch of boards with a flawed inrush limiter. I’m pretty confident that was my issue since I could initiate the device with a battery and then quickly switch to the stock PSU when the caps were charged. Obviously I still wonder why the battery could initiate start up in place of the PSU but I’ll leave that to those with more in-depth knowledge. Hopefully I’ll never have to worry about it again!

I've got the DCA Stealth. Excellent

Do you drive them from the rear XLR out on the TT2? I’ve been reading about them but it looks like the Stealth thread has gone south a bit.

Apologies if I am traversing old ground... I plan to order a Chord Hugo TT 2 to upgrade my Qutest. The TT2 will feed my Luxman L 505uxii integrated which has a phono amp/stage connected for my turntable. If I understand this correctly, when listening to digital sources and needing to drive speakers, I could choose to use the TT2 as a digital pre amp (and run the Luxman as separate power amp) or use the Luxman integrated analogue pre amp and use the TT2 as a DAC only. The former option will be a pain because I will need use different volume controls for analogue vs digital. The question is therefore will the SQ increases of option 1. outweigh the inconvenience. Interested in your thoughts.

Hi All,

Before I pull the trigger on my demo unit, I was wondering if somebody could share any wisdom around the "noise" I posted about before. In short, if I hold my ear right next to the volume ball / headphone jack, there is a very faint electrical-type noise. If no headphones are plugged in, this is not audible. I hear nothing through the headphones themselves of course.

I suspect this is normal?

It's from this dot matrix green screen. When the screen is not displaying anything it's quiet.
When there is something on display (changing volume etc) faint hiss (high pitch noise) can be heard.
It's pretty normal with TT2.

No this is a different sound. I know that one.

Hmmm so I would send it to Chord to have it checked. Since it's demo unit so probably comes with full warranty so it shouldn't be a problem.

I'm not sure. I think it's normal because it's not grounded. Older posts here suggest it may be.

Some people felt this tingling effect when touching TT2/mscaler - and this was due to grounding thing.
But being able to hear it ? To me that's something new.

Interesting. Is anybody able to hold their ear up to the headphone jack / ball area?

It's for sure good to hear you are all OK now.


@ the TT2 thread

Something puzzled me over Rob's 'inrush current limiter' theory and using a battery. Rob's own description of using batteries for power supplies, is that they are capable of huge 'dynamic current'. That's in his own words.

Well if the TT2 won't start with the PSU, because it's providing too much current (over 4 amps I think). Then how is the battery not doing the same, if it's capable of huge cynamic current. It's almost as if, using battery cuts of current delivery safely at or under 4 amps.

Anyway I am no expert and sincerely am not meaning to ruffle feathers. Am confused.

Also would it no be prudent for Chord to issue new PSU to TT2 owners? If a TT2 goes down out of warranty for an issue they knew about, it would not look good.
