New Portable Amp/Dac: iBasso D1 **with updates on the first page**
Sep 10, 2007 at 1:55 PM Post #1,006 of 2,626
Just bought one with over $2000 in debt at my bank, that's how much power you guys have over me.
Now it's been a day from payment and haven't got any reply over the email from them. When should I get the tracking number or acknowledgment about the purchase ?

How does the D1 DAC --> Xin Reference sound?


It sound superb! The Reference is truly the "reference" of portable amps.
With opamp changes, the D1 amp section is VERY close to the Reference. One isn't necessarily better than the other, just a little bit of difference in imaging and soundstage.

The D1 and Reference are complementary to each other, I would hate to have to choose between the 2.

The following opamps are those I have found to work particularly well in the D1, using the AD8397 as buffers. They are not necessarily listed in order of my personal preference, as each individual likely has differing tastes.

OPA2111 (DIP) Wide, expansive soundfield.
LT1364 (DIP) Very detailed, exceptional midrange.
AD8066 (SOIC) Strong lower end of the audio freq. range.
AD8599 (SOIC) Very well balanced. Very listenable.
LTC6241HV (SOIC) Most tube-like, definitive bass. Somewhat narrower soundfield.

There seems to be a very fine compliment between the D1 dac and the Xin Reference. The sound is very open, natural and free flowing. I enjoy the amp section in the D1 very much but the Reference, to me, is just a little more open and has qualities all unto itself of being a true reference, like a fine intrument. One amp may please others more than the other. I find that the D1 amp is also a very fine amp, as stated in the past in this thread and is more like a good home amp than a portable.

I apologize for my poor English but I didn't quite understand whether you were referring to the D1 DAC feeding the Xin Reference or just the Xin Reference by itself sounding superb in your reply.


D1 DAC output to Reference sounds superb. The Reference with its own analog input also is a fine-sounding amp.

HiFlight, what is the change in sound of running: H120>Xin amp vs. H120>D1 (DAC only) > Xin amp? Does the DAC noticeably improve the sound?

There seems to be a lot of variations on the LTC6241HV out there. Do you think it makes any difference other than packaging which one you get?

Tomorrow I am scheduled to receive the replacement D1 from iBasso. For those that do not remember it will replace the one I have had since 9/4 and on which the blue light on the front panel stoped working before the 12 hour mark. Excellent customer service by iBasso.

The funny/sad thing is that the blue ligth started working today on its own. ??? Besides a gremlin, any idea why a light that went out a week ago just started working w/o any work done to it? I mean I feel bad that iBasso spent money to send me a new D1 and the one I have starts working on its own 24 hours before the arrival of its replacement.

Thanks.

No, they sound the same. I would just order the PDIP configuration, as they are plug and play, with no adapter or soldering required.

About 3 days at least.

The LT1364 is available in PDIP and the LTC6241HV is SOIC or DFN, from LT anyway.

*sobs*
My wallet lies trembling on my table... he knows I cannot resist the D1.
Optical in.
USB in.
Cirrus Logic's flagship chip.
All-alum construction.

I'm ordering one tomorrow. *sigh*
