Can we look forward to a comparison of your modified Shanling cd-player and the Reference One? I hope so.



Definitely

It is nice that the Shanling has coax digital output!

Benchmark was about the only one I was seriously considering until this little gem came up. I've followed the thread very closely and really want to applaud Currawong for his excellent impressions and organizing and keeping track of the changes in the first post. Well, I'm convinced and ordered up a Compass for work and a Reference One for home/main system. The One will arrive late April once I convince my boss I need a bonus

The Compass should be here early April. I'll be writing up some reviews for both. I can't wait!



Nice Combo Order! You can use the analytical ability of your new PS-1000s to help us analyze these gadgets. What amp for the REF1?

I will have 2 major amps on hand: EAR HP4 and the Melos SHA-X. I won't have any top shelf all solid state amps, though perhaps I could request someone loan me a really good solid state amp as I review the Dacs.

Where are you located Zanth (generally speaking of course) ? I may be able to help you out with that SS amp question.

Peete.

Now the goal is to replicate the sound at this point in time I would say, as far as the bass is concerned.


Thats good to know. I'm getting too much bass out of my sr60's with the moon opamp in. Better then not enough bass though hehe.

Biggie.

Is super mode the bypass of the amp so the Dac can be used alone feeding an outside amp or preamp?

Super effectively splits the DAC and amp portions so that they can be used independently of one another (at the same time even).

The Compass and the HDAM will be all over the place in the first 350 hours so make a note of that fellow Compass owners. It all evens out after 400+ hours with quite good sound staging and other improvements well into the 500+ hour range.

Peete.

PS Zanth....I'll have to think about it. I'll contact you via PM.

Once I tried to see if there is a difference between coaxial from my motherboard and USB so I played coaxial via Foobar and USB with Winamp the song at the same time so I could hear the differences. Maybe by a very little margin the coaxial was better.

But... if you try both via Winamp the difference in sound volume is huge, more like what MDB said sometime ago after going to MediaMonkey. So one begin to think what the hell is going on as both are (should be?) bit perfect.

In this case I have no preference yet, but looks like coaxial has more extension on highs and tighter bass. The difference in volume don't help.
Edit: Coaxial has more soundstage too.

My experience with Earth said it never lost bass, only got stronger with time, the opposite was true with highs.

Edit:Happy to know PP, I'm still writing about the difference in HDAMs with time, both have 400 hours now.

I just did a quick check and that is definitely what has happened. Preamp and gain are switched.

hey peete, when do we get the next installment of your epic review? i got a chance to listen to my roommates compass last night and it sounds very good. i put the sun in my ef1 amp and really like it. will have to see what happens when it burns in more.

Ive hit the 97 hour mark of burn in. I honestly havent heard much change since the 48 hour mark. I think at the most it continued its tapered progression of refinement of the lower end to a nice balanced point. The trebles continued their increased presence to the current balanced state. All of this is, as stated before, with the Soft 2 setting (so as to burn all parts of the Compass). Im really quite curious what Neutral or Bright would sound like since its current state sounds neutral and balanced to me. Unless the Compass plateaus its burn in for a while and then starts another sharp burst of change down the road, I believe I may have hit the burned in state.

If this is the case, I am thinking that some modification is in order, I really want to play with the different HDAMs and jumper settings. The soundstage has slightly increased since its first day but nothing significant as far as I have been able to decipher, which is why I want to hear the soundstage of the Moon =O

If any of the original 18 have any insight into this possible burn in plateau that indicate that I shouldnt modify yet, please let me know =D
