Sean: It appears that the metal (?) square boxes are discrete op-amps, like the Citypulse DAC. The IC op-amps appear to be voltage regulators. It also is a dual-mono design, with two toroids and two power supplies. However, unlike the Citypulse DAC, there doesn't appear to be an easy way to...

Zool: The ground on the IEC isn't connected. LW

Jon L: My Zhaolu has the caps bypassed, 2x2107's and 1x2111. SilClear on all the board connectors and fuse, chassis damping. I have a ZapFilter on hand, but haven't installed it. Larry

Roger, Jon: There is considerably better resolution and bass control with the 7.2x than my modded Zhaolu 2.0. Over the past three weeks, I've switched them in and out of my system many times, as they sit next to each other, using the same cabling, running off a Felicia balanced power supply...

Yesterday, I took my 7.2x to a friend's for a shootout with his Meitner Bidat (stock) being fed by a CEC belt-drive transport. Other equipment included passive pre, Komura 845 PP monoblocks driving Duevel Bella Luna speaks, top-shelf cabling. We played a few tracks of his choosing to warm things...

Tower: Only one sample, but no problems with losing lock, ever. Also, the 7.2 doesn't have the turn-on pop of my Zhaolu 2.0. Switching between coax and optical inputs or upsampling is dead silent, also. I've only been feeding it 44.1 so I don't know about use with a computer. Larry

Pojen: My posts about the 7.2 only apply to its use as a DAC. In that regard, it's great. I'll be posting more as I compare it as a DAC with other stand-alone DAC's. Regards, Larry Welsh

PoJen: I don't use an external headphone amp. If you are referring to the volume-controlled RCA outputs of the 7.2, they are not nearly as good as the discrete analog outputs. I tried using the 7.2 as a pre-amp and it's so-so compared to my TacT, although it's better than many pre's I've...

Supersonic: I'm aware of burn-in, although the topology of the 7.2x doesn't include op-amps, which take a very long time to burn in. So far, I've got 100 hours on it. I haven't noticed any big change in the sound compared to the changes in Zhaolu 2.0 after burn-in. Still sounds great, there's...

Skull: I think all the units Eddie gets are congigured for 220v. The label on the back says 220v. However, with dual primary 110v windings on the toroid and two positions for the power connector, it's obviously designed for either. The 110v 4-conductor connector position is right next to the...

Maxxfell: There's a pair of analog inputs, selectable from the remote or "Input" button on the front panel. LW

Towert7: No external headphone amp. I primarily use this in my main system and rarely listen with cans. See my profile for equipment. Andrew: Eddie emailed me to say he forgot to configure it for 110v and told me what to do. No problem with warranty, there was no seal. Larry

Yikes! As impressive as the modded Zhaolu 2.0 is, the DA7.2x outperforms it in every way, even with only 24 hrs. on it (according to Eddie). It has deeper and better-controlled bass, better resolution, blacker background, much larger soundstage, faster transients, more texture. I had been...

I received the 7.2x this morning. Gotta convert it to 110v. Build quality and finish are impressive. It weighs a lot more than the Zhaolu. Impressions later. Larry Welsh

Andrew: They're both the same. For 110v operation, the input supply plug to the PCB is switched to another position. You can see the two positions in one of the close-ups on Eddie's site (two white connectors next to each other, one is blank). Eddie forgot to do it to mine so I have an excuse...

All: I just received the 7.2x tracking number from Eddie. I should have it Monday or Tuesday. Apparantly, the delay was due to having packaging made to survive international shipping. Regards, Larry Welsh

daggerlee: Yup, the click is normal. It's a relay. Regards, Larry Welsh

All: I ordered one a few days ago. Eddie replied he "will ship as soon as the product arrive." I was under the impression he had them in stock. No biggie. I'll be comparing it to 1852 and 4398 Zhaolu 2.0's, bypassed, one with Eddie's caps mod. Regards, Larry Welsh

Alex: Nothing strange. Lots of components in electronics are microphonic, subject to vibrations. You just discovered how different support affects microphonics by varying the damping (or non-damping) materials. I've tried my Zhaolu on Myrtle blocks, rollers, dead balls, Vibrapods and...

Sugano-san: I've never been able to buy neckties long-distance. They seem to lose immediacy, resolution and definition. LW

Garbz: The seller is legit, with 1189 positive feedbacks, NO negatives. A very hard record to beat. LW

The seller posted on AC that he'd sold out the first ten sets. This is a new listing for another ten. Larry

All, An eBay seller is offering sets of three op-amps on eBay, 2107, 2111 or combos, at $9.50 + $3.00 shipping. A steal at the price. Only six sets left. No affiliation, etc. Regards, Larry Welsh
