NEWS: Meridian Releases The Explorer Pocket-Sized USB DAC - Page 9

post #121 of 1026

I just received mine from the authorized Meridian dealer in Canada.

 

Using PC > Foobar2000 > SoX upsampler (24/192) > WASAPI > Meridian Explorer > JVC FXZ-100

 

So far sounds great! (only 30mins. in..) Bass is noticeably cleaner and more articulate over my previous DACs (HK3490 AKM, fiio e7, ele usb)

Sound Hounds in Victoria (they just got them in stock yesterday and shipped out to me with express 1-day service)

 Just heard from TTVJ that they're out of stock until Monday... frown.gif. With the seemingly glowing reviews I can see why! If you're on the fence, you might want to pull the trigger sooner than later. Very excited to get mine next week (hopefully).

Wow they had ample stock the day that they were released and new stock today and they are already sold out again.  I am glad mine will be here tomorrow.

Not sure. I think I have a powered up here somewhere, but I haven't seen it in years. 

 

Anyone know a good powered hub to buy? 

post #128 of 1026

Just got back from Talk of the Town A/V in Allendale, NJ where I bought the first Explorer two days ago.  They still have them in stock and they do mail order also. 

 

This afternoon, Ryan Donaher, Regional Sales Manager for Meridian was there demoing the Explorer and other Meridian AV toys.

He was kind enough to answer Explorer related questions that had been brought up on this forum, so here goes:

 

Q:  What is the current draw?

A:  ~500mA

 

Q:  Will it work with apple phones/tablets like the iPad with camera kit?

A:   Not directly, since they cannot source 500mA.

 

Q:  Will it work with apple phones/tablets and camera kit and a powered hub?

A:   The powered hub should provide sufficient current.  It is unclear if the drivers are the same as iOS which works natively.

      (I guess folks with camera kit and power hubs can test this and report to the forum)

 

Q:  Will it work with android powered devices?

A:  This is not something that Meridian is pursuing directly, but if Android supports the appropriate USB class interface, it should work.

      (this is one I really care about.................someone able to test this yet???...........i don't have an android device yet)

 

Q:  What is the impedance of the headphone output?

A:   After checking the documentation that he had on his laptop, this was not available.  Ryan sent an email back to HQ with the    question and will forward the response to me.

 

So that is it for now............time to play with mine.  I installed the windows driver on my laptop this morning and the explorer makes very nice sounds with my etymotics.  I next want to see if the headphone output is further improved with my little headamp or not.

post #129 of 1026
Would you ask him what the impedance is of the line out? A lot of us will use it with an amp. I suspect it should be low.

More random thoughts on the Meridian explorer.............and why I might conceivably need more than one.

 

My application:  

I bought this with the intent of using it as the DAC in my car stereo system, where the current Kenwood 9900HD internal dac is clearly outclassed by the iStreamer.  Next, I plan to ditch apple ipod touch as my source since I find them too frustratingly closed to innovation on our part.........onward to Android (assume it will work, and if not, someone will make it work in short order) or 'something else'.

 

'Something else' just popped into my head while talking to Evan (Talk of the Town A/V) and Ryan (Meridian sales manager) this afternoon.  I was describing to them the architecture of my 'patio' system, which is a logitech Touch streaming from my home NAS, analog out to a Pelican box housing a computer power supply (+12V, +5V) and a car stereo (for amplification to stereostone speakers on the patio)..............and I stated that I was sure the Explorer would sound better than the analog out of the logitech touch.

Then I remembered that someone had hacked the Logitech Touch so that it's USB input(!) could be used as a USB output(!!!!!).

This had never been on my technology roadmap before but now it sounds like something worth pursuing.

 

If I follow this path, I would hack the Logitech Touch to provide USB output to the Meridian, and then line out to the car stereo in the pelican box that drives the speaker stones.............now I'm  jazzed again to play with my toys to get better sound.

 

So what about the car stereo system?  I've  been planning for a while to put a Logitech Touch into my car as well (just bought a used since they don't have them in stores anymore) and the plan was to use analog out of the Logitech into the AUX IN of the Kenwood, replacing an iPod==>iStreamer==>Kenwood that I had been using.  The last step, which I've been working on for the past week is getting a Squeezebox server into my car, but that looks very doable as the squeezebox server installation has now been ported to the Raspberry Pi, the $35 credit card sized computer.  

 

So, this now suggests that the plan be modified to have the Raspberry Pi running squeezbox server, wired ethernet cable between Raspberry Pi and Logitech Touch, Logitech Touch hacked for USB output to Meridian Explorer with line out to Kenwood in dash.

 

So I can see a use for an Explorer in my car system, in my patio system and when traveling on planes.  Since no one uses the car or patio system when I'm traveling, I can probably work with just 2 of these DACs

 

Q:  Dad, when are you going to stop changing all the electronics?

A:  Never, so you might as well get used to it.

Well that was easier than I'd anticipated.  It turns out that the non-official app that gives the Logitech Touch 24/192 capability on spdif is the same app that turns on the USB output, so I already had the capability (but had never had a usb input to a DAC before).

 

Hooked it up to Meridian Explorer and it just worked!  Red book, 24/96, even 24/172 samples I had downloaded for experimentation..............the 3 lights on the Meridian light up perfectly with the bit rate changes.  This is a winner.

 

The  only thing I noticed here is that compared to USB from my W7 laptop, the volume out of the Logitech/Meridian combo is much lower, and at max volume setting on the Logitech, it was insufficient with the Etys.  I suspect there is a volume setting somewhere that I'm missing, probably in the logitech non-official, non-supported app.

 

But this works, right out of the box (note:  no USB powered hub needed as the Logitech apparently has the juice to power the Meridian).

 

Now to fix the volume issue and build a Raspberry Pi squeezebox server for the car. beerchug.gif

I ordered the ME from TTVJ today.. I have a Galaxy S3 & OTG cable, so if someone doesn't get to it before me, I'll be able to confirm inter-operability as soon as it arrives (not sure exactly when that will be since it appears TTVJ is backordered & I haven't got a shipping notice yet).

where is the 'onboard analog headphone amplifier' and how is it controlled?

 

is this part of the USB specification?

 

their website says:

 

Analogue volume control for headphone output, controlled from PC, control law modified to match connected OS.

They haven't disclosed which IC they're using for this, but it's probably an SMD device underneath the headphone output caps. I spent about a half hour trying to match the power specs with TI's current set of combo digitally controlled analog volume pots with headphone driving capabilities but couldn't figure out which one it was. It might be the latest part from Maxim.

I just got mine today from TTVJ for my work computer + Denon AH-D2000s. Coming from using the headphone out of my laptop dock to this is pretty much the best thing ever. I had my headphones on all day, much to the chagrin of everyone trying to talk to me. They should know better than to come between a guy and his new hotness.
