I have that headstand too. Solid design.

I have a mojo cables accessory pack if anyone would like to trade it for a black TT2 in September?:laughing::deadhorse::deadhorse:

Just over 18V RMS at 1% THD - amp mode - DAC mode its 5V RMS.

The XLR's are balanced, so you have +9v RMS on the positive pin, and -9v RMS on the negative pin, so 18v RMS is now available.


Rob, in the TT2 specs and some of your other posts you mention the max output on the XLRs to be 18W at 1% THD into 8 Ohm, which means 12V and 1.5A.

18V at 8 Ohm would be 40.5W.

Also, could you say if someone driving speakers from the TT2 should be careful about the OP stage hard clipping and watch the volume control like with a traditional amplifier, or the max level on the volume control with a 0dBFS signal is set so that you can't hard clip the OP stage amplifier, meaning it has some headroom beyond the max level on the VC?

Yes the OP stage has emitter degeneration resistors, plus a safety R, and this limits the available voltage with a given current. This is entirely usual in a power amp design.

If you run at or below +6dB on the volume, it will not clip - with CD as a source and a 8 ohm SE load. With Blu ray discs, I found you could run at +12 dB, and it never clipped in practice using J River.

Super (or ultra)capacitors are recently becoming popular for outboard power supplies like the ones from Vinnie Rossi or Uptone. One advantage is their much longer lifespan compared to batteries (not the problems and costs with exchanging batteries for Mojo ertc.) and lower noise. I wonder how long the TT2 can play when not connected to its external SMPS.

Do the super capacitors help the performance of the dac or is that further down the chain,in other words say I'm listening to my hugo TT 2 as a dac only do the super caps come into play or only when I'm using my headphones or playing the hugo TT 2 directly to speakers?

They help the performance of the dac. The tt2 psu benefits all lines out..

I've been listening to my oppo 205 and it's not bad, now it's run in it really is quite enjoyable and the longer I don't have my hugo 2 the better it's gonna sound so come autumn it's gonna be quite a shock

Going cold turkey ? Think you’ll last till autumn?

Is the acrylic looking coloured orb on the front the volume or sample rate or something else maybe?:thinking:

It basically doesn't. Rob stated that they discharge quickly without power.

As far as i understand it takes 10 seconds for the supercaps to charge up so does that mean the TT2 is inoperable for 10 seconds after being switched on?

Listening to Chris Botti on trumpet La Belle Dame Sans Regrets Roon. Hypnotising just as dawn is breaking.
