DAC for iMac System


Looking for advice on a DAC, under $300 used, for iMac-Onkyo A9555-Era 4 desktop system. Would like to use USB, will not need headphone, volume control, just a direct hookup to amp. Already have USB cable and RCA interconnects. Thanks.

Willie, I am sure you are correct given that a new Bitfrost with Uber retails at $550. Would make for a great deal at $300 used. Maybe in another year? I am tempted to try out a Modi for a second system and would like to hear from someone who has one.

I see that Music Direct is selling the Moon 100D DAc for $325. They allow 30 day return. I have no experience with this DAC but it has gotten positive reviews at a retail price 2x the MD sale price. I would be tempted if in the market for a $300 DAC.

Though I have not heard the Music Hall 25.2, I trust Ctsooner's recommendation if one could be found within budget.

Anyone heard the Music Fidelity V90 ($300) or the Music Hall 15.2 ($300)?
I had noticed the Simaudio 100D but after reading up on it, was left wondering if it really was meant for USB use.
Jl35 - as much as I like Moon gear - I have one of their phono stages - you are correct in that the usb interface as they have implemented it is lacking.

You would need a USB/spdif converter, like the v-link, to bring it up to the performance of the other inputs.

Re: the Modi - it's upper limit is 24/96 - what do you require?

What about the Cambridge Audio Dacmagic 100 - $299
Looks pretty impressive - but I haven't heard it
It will process 24/192 via the usb input, but you have to switch it to USB-2 mode.
Reviews seem quite positive

Something to ponder :-)
Right now probably leaning towards the Modi - thanks for all the recommendations...
I have heard a bunch of the sub 2k DAC's since I was in that market. I wanted balanced since my Ayre is balanced. Most under 1k aren't balanced. I thought that most of the sub 1k DACs didn't do piano correctly. Too digital for my ears and my system. The MH is just right for the money. Even the RCA out with the tube sounds great. most folks with this price DAC don't have ultra high rez systems and they can often be too tizzy on top. The MH was one of the only DAC's I heard that was more analog like. I heard the top Shitt system and was unimpressed. It was just ok to me. What some pass as high rez, often times is just digital distortion on the high end and it creates listener fatigue. The MF V90 didn't do much for me other than give me a 15 minute headache. That said, it could have been the system I heard it in, but even the store owner didn't like it. He preferred the MH 25.3 which he had just picked up. Roy Hall has always offered you more for your money. My DAC is in a 10k plus system. I feel that digital is about to change dramatically and I don't want to much wrapped up in products that will lose their value greatly over the next few years, so a new 500 DAC made sense to me. That's just me. I also heard the Cambridge vs the MH DAC's side by side and it was no contest. I have heard all of these DAC's on speakers that were in the 5-10k range and with top of the line electronics and cables set up properly. Some DACS just sound digital to me (most). I leave it on all the time an it's fun to listen again. I spend hours a day listening now.
