SPL Phonitor Roll Call & Appreciation Thread - Page 22

post #316 of 678

SN 11.2731.00176 (Model 2730b) checking in here!

 

Though I've had it for almost a week, I've only gotten to listen to it for about two hours, and that was yesterday. I'll post more detailed findings and impressions once I've gotten to spend more serious time with it. :-)

 

I do suspect that my DAC (HeadRoom Mico DAC) is bottle-necking it somewhat--I wasn't honestly planning on getting a Phonitor, but a deal came up that I couldn't refuse, and I had the cash for it, so I went for it. I'll be upgrading the DAC sometime down the road a ways.

 

Initial impressions are still very positive though--especially the sound-stage and the bass control/detail retrieval.

Sorry for the thread resurrection guys but was wondering what OPA's I could use in my Auditor? I was looking to get the Burson's and just bend the pins so they sat at an angle, but which ones do I use? If you know of any ones that are good alternatives to the ones already in the unit then let me know. I want maximum performance from this thing and want the most neutral sound I can get.

Te most neutral opamps are already in place

post #319 of 678

Oh? Well I've read the amps an be a little bright and I was hoping to have a flatter response here. I don't want brighter than neutral. Even slightly warm would be OK as long as the soundstage, imaging, and extension are great.

With audio GD ref5 these are as neutral as it can get (opamps). It really depends on the DAC. With Auditor you will hear what you feed it with.

I got my SPL Auditor today and man oh man it's really good! Beats my Roc to a pulp and my WA3+ as well. The sound is so smooth and effortless. Really a nice sounding amp.

 

I also went a head and filmed an unboxing of it and am uploading that now.

Did you buy yours new? Because when I got it it sounded really harsh for the first 30 hours.

post #323 of 678

Yep brand new. Got it from Front End Audio for $899 and it's well worth the full $999 price IMO. To me I did not hear any harshness at all. I heard some slight harshness on my V800 DAC when I bought it but now after maybe 200 hours it sounds smooth. Now I don't believe in headphone burn-in but I do in gear because capacitors and resistors can change.

 

As for the Auditor I have been playing around with the different headphones I own and found that the K702 and HARX900 sound really good on this amp.

 

On my X-CANV8P the K702 sounds incredible but on the Auditor it go's to another level. The K702 sounds so full and natural. I think this is due to the higher output impedance of the amp. It just sounds so much better on the Auditor, but on the ROC it's still a bit better. A balanced K702 sounds better than when in single ended mode on my set-up.

 

The HARX900 gains so much bass and sounds smoother and a bit less up front. It kinda took a step back and became more reserved but in a good way. The headphone gained much needed mid-bass IMO. To me it just sounds much better on this amp.

Just got mine brand new from SoundEarphones. I didn't even have to argue for a pricematch, they just gave it to me, with free shipping. Great company.

 

I've been listening through my HD800 practically all last night and this morning. Came back from work yesterday, got the package, listened for some time. Went to sleep for 4 hours, woke up, and listened some more. Too bad I gotta head to work in an hour. Detailed comparisons tonight.

 

Initial thought with HD800: Imaging is absolutely amazing. Holy grail of monitoring, perhaps? I also played around with the crossfeed, but couldn't find a good configuration with HD800. I feel that HD800 is a brilliant imaging headphone on its own, any attempt to alter the imaging will simply ruin the sound. This is where I found the quality of the crossfeed to be outstanding. Even though I couldn't find a good crossfeed setting (will try more tonight), having crossfeed on did not ruin imaging like all my previous attempts with various crossfeed DSPs. The crossfeed simply works in the background without you realizing.

 

I have never heard such a good presentation from my HD800. Looks like I will be keeping this amp for a long time.

 

Tonight, comparisons with my other headphones and other amp/DAC.

What are original OPA's in side the Auditor?

post #326 of 678

So, no knowledge about the OPA's in side the Auditor?

They are made by SPL so best to ask them. They are not something you can buy as standalone.

okay, I'll ask them ...thanks. 

post #329 of 678

This is SPL replay to my question, what op amp there is inside the Phonitor/Auditor.

 

Our op-amps are the core elements of the 120V technology ... these are hand-made components which would never fit into any other unit :)
And these are no ICs - as single components they look like this :
 
120v_opamp350.jpg
 
 
In the Auditor, they are fixed on the PCB - you cannot exchange them. 
This is how the Auditor looks like internally (pic shows the first two of four opamps ... this also explains the housings's depth, as we simply need space for this stuff :)
 
AUDITOR_PCB_opamps_mark.jpg
 
 
The area marked red: that is an op-amp. It is a discrete design, no chip/IC component. Nothing can be changed within this circuit.
the area marked yellow: this component (LF 411) is used in a circuit to cancel DC offsets. It does not work with audio signals directly, therefore no influence on sound. Do not (!) change it to ensure proper function.
 
We do not see a chance to "tune" Auditor or Phonitor simply by component exchange -- we already did so :)
 
Thanks to Paul from the SPL support team.

I exchanged the opamps with great success. Now sounds completely different. Not sure why the state you cannot tune the sound.
