New OPPO HA-1 (CES 2014) - Page 14

As me and my ears get older I find myself longing more and more for that rich, meaty sound my memory associates with vintage gear.

My impressions in the other thread state that the HA-1 isn't cold or analytical at all. As mentioned, I was going to sell my LCD-XC because I found them to be too forward in the upper mids/treble, until I purchased the HA-1. With this combo I find the dynamics very punchy and the bass/lower mids very present and detailed. The bass texture is simply outstanding and sounds very, very natural, very real. The DAC is very much neutral to me with no cold or warm signature. What I feed it is what comes out with every nuance in tact.

The HA-1 has allowed the XC to perform to their full potential. The same goes for my other headphones. When I'm in the mood for a different sound signature I simply reach for different headphones now instead of trying to find the right synergy in the rest of the chain. HA-1 simply is a natural honest amp that fills the space of the headphone that's plugged in to it.

One thing that I would like to see (and I know others will strongly disagree) is bass/treble control. Not a full EQ but something to add a bit more flavour when the mood strikes. Much cheaper than tube rolling a tube amp (but not half as fun)!

I've owned pure Class A amps in the 80's. These were 100w/ch + monsters and you could cook breakfast on them.

 

I now own a Nait XS 2 integrated which has a Class A headphone output.

 

The whole thing runs cool as a cucumber even when I push it. FWIW the HP output is nothing to write home about.

 

I totally agree on the bass/treble controls. With today's technology it can be done without affecting SQ including a defeat button for those die hard flat earthers.

Sounds like you want a a Rega a Dac or Yulong D18. I own he Rega for the exact reason you stated and had looked at the d18 based on reputation.

Firstly, the ESS9018 can be used as an 8 channel DAC. In fact on the 105 I believe that is exactly how it is used. I seem to recall 4 of the feeds are used for the stereo output, 2 are not connected, and 2 are used for the headphone out. But to get the maximum SNR and dynamic performance you use 4 DACs per channel. Based on the specification of the dynamic range for the HA-1 in the DAC stage (115dB), this would indicate to me they are not using 4 DACs per channel and have probably split it again to cover the pre-amp output.

Secondly, there are the choices of op-amp and capacitors as well as the power supply aspect that all affect things. I don't believe we have enough data to judge that either at this point.

As far as I can tell from the white papers on the ESS9018 the eight channels are used concurrently to reduce signal noise (simplified summary). The DAC also outputs a balanced analog signal so I believe it would need all channels to provide the signal in balanced mode (4 per side). Correct me if I'm wrong as I'm not an electrical engineer, and I don't know how they implemented the DAC in to the design. I do know that there is absolutely zero noise in the HA-1. None, zilch, nadda.

As far as op-amps I'm not sure what the HA-1 uses, or if they use any. The web site states they use discrete transistors in their fully analog design not op-amps, but again I don't know for sure.

Yeah, it can be implemented that way... I think he's implying the BD105 doesn't have the noise reduction by running concurrent channels as it supports more output channels.  So even though they use the same ESS9018 it doesn't mean it's the same quality stereo dac implementation

Tried the Rega at home for a day. Liked its warm forgiving sound but found it lacked in the PRaT department. Would like to hear it again.

 

Owned the Yulong DA8 for a couple of weeks. Liked its detailed sound and good dynamics. Just couldn't stand its unforgiving top end.

 

Still own a modded EE Minimax since it first came out. Good compromise between Yulong and Rega.

 

Still searching for a replacement. Haven't heard it yet, and the price kills me, but have a feeling it might be the Chord Hugo.

post #202 of 223
I hear some great things about the Hugo. Anyone own both Hugo and HA-1? Or at least heard them both for comparison?
post #203 of 223
I leave my Rega on all the time. Even if turned off for an hour it sounds bad initially.

I hope you find that replacement because I'll probably get one too. I need something for another system, I'd like to naim dac v1, but really want something in that $700 - $1k range. Was hoping ha-1 was going to be it.

Has anybody from the UK or Europe ordered an HA-1 from the States,I just wondered if it worked out cheaper than buying from the UK.
post #205 of 223

Does anyone have recent info on when these will be available to buy from Oppo's website?  The "estimated availability" just moved to July.

Only Oppo Digital can answer that, and they usually keep that info tightly wrapped up. Better keep your finger on the trigger because I imagine they'll sell out if you're too slow.

I’m wondering if maybe I missed the June batch.  I signed up for the email list, but I didn’t receive any word from them.   

I find it very frustrating that Oppo is handling whatever supply constraint they have in this way.  I’d place an order if they would give me a delivery date.  But I’m not confident I will be lucky enough to get in an order when these become available.  Also, I’m not inclined to trust the July estimate given Oppo said April, then May, then June…

The HA-1 has been available for a couple months. Many people have purchased them.
They have just simply run out of stock a couple of times due to high demand.
The July release date you see is only there since they ran out of stock again a couple weeks ago.
You could try calling them. Perhaps they will take a preorder from you if you ask nicely.

Yeah, I bought mine from the first batch about 5 minutes after it was released and it was sold out shortly afterward.

I've listened to the HA-1 through my Krell electronics and Thiel 5 speakers (~ 1 month). The music is meaty and captivating when you have good recordings. Lots of detail and texture that make you want to keep listening and NOT run away. I've compared it against my Benchmark USB Dac-1, which I do like, but I've found myself listening to a lot more music through the HA-1. I'm keeping this unit....... Oppo gives you 30 days to figure out the HA-1 for yourself. Enjoy!
