Pt-100 --Dac using what chip set ?

[kauai82]

What chip set is the PT-100 and TA-100 using in the DAC section ? Really like the sound of DAC in my PT-100.  Matt

[kauai82]

No one knows ?

[novisnick]

I don't know but it does sound very similar to my DC-1 which sounded very similar to the XMC-1. Don't call me out on it but I'd claim they're the same DACs

They may have the same Burr-Brown DAC the Big and Little Ego use or maybe a Cirrus Logic DAC. I do not think Emotiva uses the Wolfson DAC but I could be wrong. Whatever the DAC used it performs very good according to reviews.

I thought the Big and Little Ego use the AKM Semiconductor DAC.

It's an AD1955a DAC. Look on the Emotiva website. Nice big picture of the DAC chip.

Hi kauai82 -

I, also, like the sound of my PT-100's DAC. In fact, I like it better than the "top of the line" Sabre DACs in my new Oppo UDP-205. How Emotiva gets such good sound out of such modest gear, I don't know - but the PT-100 is an absolute winner in my book!

I would like to point something out to those who may be new to DAC chips....
While Sabre DACs are indeed technically "very good DACs", they have a distinctive flavor or "house sound".
They tend to boost or enhance details - the result is that they either sound "more detailed" or "grainy and harsh" - depending on whether you find their sound pleasing or not.
However, they do NOT sound neutral.

So, in general, Sabre DACs sound somewhat different than all other DACs (most other DACs do their best to sound neutral).
(Note that the distinct "Sabre sound" may be more or less obvious with different circuit designs.)

I liken it to sharpening of images. A little too much and it looks artificial.. or should I say.. less natural.

Interesting comments as I've been somewhat curious about the new Oppo 205 myself. Thus far there is not a lot of information/reviews (professional) on the product but I have found a number of consumer reviews that indicate this new Sabre Dac is considerably different sounding than their predecessors including folks who have owned the previous generation 105 model. And I know of a few people who have the Sonica DAC (same chip as the 205) made by Oppo claiming similar results. This would leave one to believe that perhaps Sabre has veered away from their traditional and distinctive house sound which personally I don't care for either with this new dac chip.

That said, at least in my system I don't find the Burr Brown DACS in my XMC-1 to sound anything like the AD DAC in my ERC-3 or the DC-1. Whether that has more to do with the way the signal is sent, i.e. coax cable, HDMI, transport or what have you who knows but they do sound different.

Thanks

The Oppo BDP-105 DAC, to my ears, sounded quite like the DAC in Emotiva's PT-100. Both were relatively neutral with good sound-stage width and depth.

The Oppo UDP-205 DAC, to my ears, sounds like "Home-Theater-In-A-Box" products. Both Sabre & Oppo made a major step backward with their new implementations.

Can the sound of the Oppo be modified by a firmware update? Time will tell. And I suspect that the pressure will be on to make an improvement, because apparently I'm not the only one hearing bad things from the UDP-205.

Time to write to Oppo...
