DAVE's Popped In

Posted by: tonym on 20 January 2016

On loan from my trusty dealers, I've been feeding him a diet of room-corrected Amarra music files from my Mac Mini via USB iFi supply and from my USB/SPDIF convertor through BNC. He seems very keen on everything I've given him so far, and is performing some excellent little tricks; like extracting more detail, giving bass a clearer focus, and adding rather a lot to depth of image, the latter quite striking. We've become very good friends over the last couple of days and he's indicated he'd like to stay here.

As you might have gathered, I'm rather enamoured with Mr DAVE. Purely platonic of course. He's got lots of inputs and several rather dramatic display options, four in all (or off completely). He's more or less the same shape as my trusty QBD76 HDSD, as can be seen in the photos :-

Hi Tony,

Interesting that the brightness in vocals was the same complaint I had with the 2Qute. Perhaps if they put the DAVE chipset with a battery supply they would have a winning combination.

Although the Hugo doesn't have a buffer system Audirvana does and this may explain why it sounds better through the AV software.

Anyway you've saved yourself a few bob. 

See you next week.

Perhaps it would be trying the good old nDac again, given that the new firmware has altered the sound in a way that most people prefer. Others seem to prefer it to the Hugo: well, one other at least. We can call him Graeme. 

I heard the nDAC with the new firmware upgrade the other day and it was impressive, but I want fewer not more boxes and, for the same reason as Tony, I don't think I'll be going there.

I felt the same about the 2Qute after going back to Hugo and this came to mind reading the post earlier this morning. 2Bright would be more accurate a name...'new' Naim Dac & XPS sounding fine HH!

Perhaps the wrong thread to mention it, but I'm currently running-in a 2Qute. It arrived Christmas Eve and has clocked up about 250 playing hours so far (mostly unattended I might add) and I swear the thing is still running in! It's been quite a fraught and frustrating rollercoaster experience and along with numerous tweaks to the playback system, I think I'm getting somewhere. Perhaps not quite there yet, it was sounding incredibly cavernous and detailed last night but perhaps lacking a bit of 'flesh on the bone', right now it's sounding spot on and lovely.

Tony, I know it sounds like a fundamental consideration, but run-in is taking an age with my DAC, it might be similar with DAVE.

Until a week or so ago, I'd just substituted the DAC in my system and let things run their course whilst the rest of the system remained stable. Then ran out of patience, and snapped! I re-evaluated a lot of things in my system, for anyone interested, these are things that made a positive difference:

1. The standard Naim mains cable on the SN2 was faulty in some way. Well, it didn't sound as good as another Naim cable I tried, so it's gone and replaced with the better sounding one.

2. The Tuner input sounded fractionally better than the CD input, so I'm now using that input

3. I have no other sources hooked up the SN2. In addition to the normal mains earth (in the IEC cable) that provides chassis earth, I have a separate earth wire from a mains earth connection that provides the signal earth reference. This used to be connected to signal ground at the SN2, it's now connected to the earth terminal on the back of the 2Quite instead. This made quite a substantial difference.

4. I drive the 2Qute using Audirvana on a mac-mini. In the Audirvana system settings, I've changed from Integer mode 1 to Integer mode 2

5. I've set Audirvana to perform 'power of 2' upsampling, but limited it to a max upsampling of 192Khz and 24bit. This and item 3 were the biggest improvements of all the tweaks

6. Not to forget: Run-in, Run-in, Run-in. Lots of it!
