I guess since it was holidays there I will get a confirmation # soon. I ordered it on Sun.

Oh no...have you seen the Australian dollar recently? It's fallen 29% since July! But I want one!!!! Maybe I need to sell off some stuff...

Yesterday (10/5/08) I did a side by side of the D3, Reference, and the SR71A. They had about 85, 550, and 250 hours of burn in respectively.

For cans I used the Yuin PK1 and the Ultrasone PROline 2500. For source I used a Denon DVP-NS300, the IC was an RCA to Mini (copper) by Kimber.

The reference continuous to be the darkest of the three, IMO it does not have the treble extension the other two posses. The SR71A had the widest soundstage w/ the most powerful and deep bass. IMO the D3 was the most balanced and best sounding of the three. It offers the clearest and most detailed presentation.

In the past other amps by Ray (Hornet and Tomahawk) have taken very long hours to be fully burnt in. So I will continue the process and compare them again when the SR71 reaches a total of 500 hours of burn in. By that time the Reference would have 800 and the D3 about 350 hours of burn in.

The D3 is shaping up to be one killer of an unit at a very good price. At the next level (about 10 days away) I will also throw into the evaluation the MiniBox-E+ in stock form (AD8610) and w/ the AD797 op-amps.

I look forward to hear your impressions against the Minibox-E+. That is the only headphone amp I ever owned, so I would have trouble comparing just from memory.

I will be upgrading soon. D3 is on my cross hair.

I'd be interested in how it drives the HD650.
This amp looks very very good, especially the DAC.
Anyone tried using the DAC to feed any home amp?

hi mrarroyo,

have you noticed any significant difference between a out of the box d3 and one with 85 hr burn in?

 

[arvee]

My P3 has 50 hours of burn in with LT6241HV in LR, Bypass Buffer, LM6172 in G makes my DT880 03 250ohm sings vey nice

Good Job iBasso

It drives the HD 650's surprisingly well, perhaps not the same 'sparkle' that I get from the DV 332, but still a great sound. If it were my only amp I'd be very happy with the price/performance.

I have used it as a DAC only with my DV 332, and its pretty good, the difference between the Beresford and the D3 DAC are small, and in favour of the Beresford, but not such a huge deal, in both cases the sound coming from the HD 650's was pretty dammed good.

I've spent so long listening on cans these past few weeks I'm sure 'her indoors' thinks I'm having an affair!

How does The P3 sound with your super.fi 5pro?

 

[arvee]

P3 in LT6241HVmain,buffer bypass,LM6172ground imo makes my SF5p become too dark and too bassy but with the right op amp combination i'm sure P3 will make nice sinergy with SF5p

 

[tomjtx]

Got my D3 tracking # this am.
Should receive the amp Thurs. or Fri.

sigh of relief

You might try adding the transistor buffers included with the opamp kit. I am using the OPA2134 for the ground channel.

The D3 drives my HD650s effortlessly. I am using the D3 DAC to feed my Head-Direct EF1, and it sounds superb. The D3 DAC is able to stand up to very expensive competition.

The quality and performance of the D3 belies its modest price!

Perhaps if iBasso doubled the price and called it an "Audiophile Mark 5" or something of the like, more people would take it seriously!

 

[tha_dude]

Very intriguing, I hope we can get a detailed comparison between the D3 and Pico DACs soon...anyone?
