Switched to balanced cable and.........eek.gif blew my eardrums out........ Volume down.......

So I don't need to blindfold myself and say I can't tell anything, as it is all too obvious.
Of course I didn't even start about all other types like the tube and hybrid tube/SS and then transformeless add infinitum and choke and die over all this.
So I won't.

This is about oppo impressions so time to cough up and just say it.
So I have the unit and I won't beat around the bush.

I can say beyond shadow of a doubt that if you were to use as a dac or amp alone it would be in the utter top in it's class.
It is a killer combo.

The main description I would give it as having an extremely clean and transparent sound.
Extremely realistic with its dac sounding extremely clear.
Nuances throughout the spectrum sounding solid and true.
just plain real with this air of "clean" about it.
Trebles almost don't have any SS or tube quality, just a super clean maybe tingling trebles.

There are few amps that can fill the "void" of space that the hd800 presents.
That's why it's soundstage may sound exaggerated on some setups with less resolution, and that is why the hd800 sounds better high end equipment and with tubes, it scales as high as you can go..

But the HA-1 pulls off a surprisingly detailed and large performance, to fill in all that the hd800 portrays so as to make it seem normal.

As for some comparing the HA-1 to lesser amps and trying to downplay it's superiority,
That's on them.
As for me I was surprisingly convinced in the first 5 seconds of listening that this oppo is the real deal, utterly impressive.

I also switched using it as a dac alone and as an amp alone.
The main impression left is utter sheer transparency and clarity thru and thru.
Extremely clean clear sound.

Also just to make things more interesting to you, as to where I stand...
I am not an oppo fanboy,
I returned the PM-1 due to not being up to par compared to my hd800 and Ultrasone ed8.

Also looking at this pic you can see where my love is, for my woo wa7..
I love tubes and I really didn't think the oppo had a chance..
My woo wa7 + wa7tp combo is another excellent peformer for the amp only, not it's dac.
I wouldn't have anything else with these two amps right now.
Take my enthusiasm as you will..


As I was listening, testing the DAC and the amp separately and together, formulating my impressions, I read this (missed your post until I saw your pic).

All I can say is ditto. What a truly amazing setup. Wow. Everything you have described is what I would have tried to convey, only with my LCD-XC. I would add that with other setups I would have kept my LCD-2 rev2 (for sale?) and considered the differences to the XC to be a lot less. Through the HA-1 the 2 sounds like it belongs in their price bracket and the XC really pulls ahead. Your description of the amp filling the space of the headphone is spot on, but not limited to the airiness or soundstage. I find the bass fills in with detail and impact without increasing in bloated quantity. I can clearly hear more lifelike bass. So natural. This was one area I worried about given the relatively thin sound of the XC compared to the 2.

Listening to Baraka: the Deluxe Edition I feel the music. I feel the people. I'm there and I don't want to leave.

By the way, your setup is exactly what I was considering just to get some tubes in the mix with the HA-1 (and they look great on the top of the HA-1 chassis). Would you say they compliment each other well (haven't heard the WA7)? How do the amps compare? Not really interested in the WA7 DAC, just the tube amp.

Another pic. Gotta share.

Hey I'm looking to get the oppo base (wood + acrylic??) for the HA-1 as seen in the below pic - Anyone know how to obtain one???

 

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality

 

Peace....:L3000:

Well, there is no such well-known truism that op amps have different sounds.   Just oft-repeated anecdotal stories on Head-fi - and the plural of anecdote is NOT data.   That being said,  I am willing to grant that there may be sonic differences in tiny CMOY amps - but those arent exactly the paragon of amplifier design:  limited current capabilities, weak power supplies and massive amounts of feedback.      We are talking in the context of higher-end amplifiers, with beefy toroidal transformers & robust current and voltage capabilities.   

 

However, if you believe that every amp has a massive sonic signature, that's fine - you hear what you hear.  I think the point is that what you hear is not necessarily repeatable by others (not that it has to be, either).

Thanks.  This thread was getting kind of silly (and boring).

I think you should head over to the sound science forum and get this off your chest.  It will make you feel much better.  :wink:

More impressions with the XC, please !!!! The bass...oh, how does the bass sound ?? 

 

Sorry for that...been waiting a bit for your impressions LOL

Mine was actually on High Gain when I received my unit.

Exactly on point with design.
I am not saying differences are massive,
Just clearly and noticeably different...

My B&K amp
My Acurus amp
My Carver m500t amp
They were all extremely excellent sounding and powerful amps.
They ALL SOUNDED DIFFERENT. ..
And it was easy and instant to tell.
It's not just the raw information you hear, it is the brains interpretation and "perception" of this..

The B&K had sweeter violins.
The Acurus had more solid impact and dryer focus on the strings.
The Carver had a wet details to the the trebles with the power of the Arcam..
That is just from memory and not the whole picture. .

An analogy is like When you try on different sunglass, their color quality, the clarity, also polarized or non polarized. ..
Even if two companies try they can never be perceived the same.

I have come to realize that the sonic differences of a circuit or amp are not because of its design goals, which in theory are clear and perfect...
but it's traits of flaws or limits or how it "reacts" in real world conditions.
Getting into choice of parts & materials is another endless topic.

Nothing is a perfect as it is on paper and can always be made better.
Yet the closer to perfect anything gets, the harder to pin it down with any sonic attribute.
As it approaches utter clarity..
Like what we have with this Oppo PM-1 (!)
So I would pin the sonic trait of "clarity" to the oppo tongue.gif


The human ear not only can percieve sonic differences,
but it goes further with the brains processing, and comparison to memory, and how it interprets what it is receiving as a whole..
It is much more involved than sheer specs can possibly convey.

As you further train your mind to percieve more, the trivial things become major.
So the appreciation level rises when you have a piece of equipment like the Oppo HA-1, that satisfies.

OPPO HA-1 Headphone Amplifier Review

Secrets of Home Theater and High Fidelity - John E. Johnson, Jr. - May 15th

 

 

Here is a video that describes the main features of the HA-1

post #223 of 4844
I noticed the amp gets very warm, approaching hot. The screen also was in off position.
Not sure I like that the temperature change from this type heat to cool in long term but the quality is very impressive.

*Edit* the video explains above it slipped my mind the heat because it is a class A amp so it's fine *

Also noticed I connected fine to my andriod phone without that little antenna but my room it is within 5 feet..
Left unit on all night playing with headphones connected. .
Now time to listen smily_headphones1.gif

If i only have SE input but with balanced outputs, would the power quadruple as well? thanks

Being its a class A amp yes its does get a bit warm around the heat grill on the top, not terribly in my experience but does, depends on the ambient temp of the room, and if you gave the unit adequate breathing room.

 

Testing Bluetooth without the antenna?   Normally with the antenna you can have a range of about 30 feet typically.
