Hi @ray-dude.  I was lucky enough to hear a dc4 powered DAVE a couple of weeks ago, absolutely amazing what the DC4 does for the DAVE.

 

Now, I have a TT2 - would you say it scales the same, just with the audiable effect of having fewer taps?  Does anyone have a SJ DC4 TT2?

 

The addition of an mscaler, whilst nice, I can take or leave to be honest - I have a definite preference for PGGB.

 Gavin, @ray-dude tagged me so here I am!!

 

You and I are in direct contact already on other matters but just on what you asked about a DC4 TT2, no I have not tried that but by a strange coincidence I had a random notion to connect a DC4 to my Qutest on Sunday when a friend came round to listen to the new Innuos 2.0 app playing some PGGB files. Anyway as a finale to that session I connected a 5V DC4 to the Qutest (it had been powered by a Farad Super3).  Well, it took about 3 seconds before he turned to me with a HUGE grin on his face and just shaking his head in disbelief.

 

Let me say that the DC4 makes a STUNNING difference to the Qutest. Trying it with the qutest was not meant to be  realistic or practical proposal because the qutest costs around £1,200 in the UK and the DC4 costs £4,000 but it has really made me wonder if that £5,200 combination can compete with and be better than other DACs in that price bracket. It really does sound sublime. The bass texture, definition and depth is unreal. The top end is silky smooth but detailed at the same time. Am I gushing? Yes I sure am. It was a surreal sound. In fact it still is because I have left the DC4 connected to the Qutest.

 

Would it do the same with a TT2? I have no idea but when you visit me next week you can bring your TT2 and we can try it with a DC4.

 

PS, you will realise that I will want to pit my DC4 Qutest against your new DAC which is around the same price!

 

Does that help?

Game on, I'll also bring my TT2.
