As posted before, I use AD797 at I/V for almost a year and they are hot but never overheated.

E1 case dissipates heat very well, even during hot summer.

I should of used a different word. It's not overheating, but too warm for my taste i guess.

With them on the I/V channels are O.K. Only a little worst sounding than the Muses but for a lot cheaper.

 

The Essence one does dissipate heat well, but my unit is new and the smell is pretty strong.

I'm thinking of buying the Muses op-amps for the I/V and LPF stages.

Should I buy something else for the buffer stages or should I keep the default op-amps?

Muses are good.

 

I use LME49710HA's over the LM4562's (XLR/RCA Buffer) and LME49720 Headphone I/V LFP. They sound better.

The dual LME49710HA modules are easily the best unit to build out of that opamp family.

I won't be needing the LME49710NA's from you any longer, sorry Robeh.

I needed them urgently.

 

Decided to make my own metal cans on 2oz copper pcb, gold plated contacts, and 5% silver solder.

Put them on the headphone I/V & LFP replacing the LME49720NA's.

Has to piggy back them on some gold plated DIP IC Sockets as they interfered with the headphone volume, plug socket, and capacitor.

 

Looks something like this.

1000

 

Heard a some positive changes compared to the LME49720 via Headphones. I'm liking these metal cans.

Can't really hear much difference out of the RCA Output as i listen to too many upbeat songs, will switch to classical and listen for changes via Speakers.

Hey guys, where did you get the MUSES from? I can't see them anywhere. Digikey doesn't have them in stock and it's a non stocking item.

 

Does somebody have any impressions on the LME49860 for the buffer stage?

post #1028 of 3016

I might get the muse edition, and while checking the asus site, I did not find any drivers/firmware listed for it at:

 

http://www.asus.com/Multimedia/Audio_Cards/Xonar_Essence_One_MUSES_Edition/#download

 

 

So I should have the latest firmware & divers when I get it?

 

Still shifting between it and the DAC1, so any help is appreciated.

That's fine.  Holidays are a busy time, if you needed them ASAP, you should have stated that fact. 

Anyway, Sound good don't they?

They only have 1 left now, the last time i checked they had 19.

 

Ebay sells them but a tad more expensive, if you get 6 on ebay, it's $23.02 more. (That's if considering that digikey ships for $9.69 with a 9.75% tax)

I got mine off ebay and received it in 2 days even though it's from China. I've verified that it's genuine.

Use the same driver as the standard Essence One.

The only difference between the two is the MUSES01 op amps and gain switcher for IEM Earphones.

 

After updating, it should look a little like this:

didn't need them super ASAP or anything, it's just it felt too delayed so i ended up making my own as i needed to finish the review.

 

They sound good, i like them over the LME49720. Their graphs also measure better which is a uber awesome.

When using the 49710HA's on loud speaker volumes, there's a slight difference, i can't fully pin point the area of sound that it improves, but i know fully, that it's there. I must have swapped out between the two at least 30 times. On headphones (mainly the HE-500), there's 3x as much difference than on the RCA Output which is also running the 49710HA's over the LME4562.

 

Once i grasp fully it's improved areas, i'll let everyone know! gs1000.gif

Thank you, What is the difference between the USB firmware and the MCU firmware?

The USB F/W is for the Audio Chip. (0111)

The MCU is for everything else. (1.27)

 

Have you gotten the Essence One yet? If you haven't, i recommend getting the regular one and buying the muses01 op amps separately.

 

It will be more cost effective and giving you some leftover NE5532 op amps that can be used to compare to the muses. (NE5532 are very bass heavy/boomy, clouds the vocals, no good instrument/vocal seperation, lacks detail, lacks realism, no 3D sound)

 

Update:

Got my TO-99 Heatsinks for the LME49710HA's. Feels good to have cooler op-amps. Overheated workers do sloppy jobs.

Can't hear any differences in SQ, but hey, it was only $4 and i feel as if it was money well spent.

Have been waiting on my LME49720HAs for well over a month now (shipping affected by sandy), unfortunately it doesn't look like I'll be seeing them anytime soon. I decided to invest in 4x LME49710HAs from cssarrow's suggestion.

 

Any advise on where I should slot them?

This is where i got them

 

Do It Yourself:

http://www.ebay.com/itm/390422337315?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

http://www.ebay.com/itm/180728972287?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

http://www.ebay.com/itm/261027708584?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

http://www.ebay.com/itm/250975939649?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

 

Heatsink not required, but if you do get it, you'll need a dremel to cut off some fins so they do not touch the pcb/each other

+Time and Silver Solder (pointy soldering iron recommended)

 

Buy Them Pre-Made

http://www.ebay.com/itm/LME49710HA-X2-Adaptor-/180872434827?pt=US_Home_Audio_Amplifiers_Preamps&hash=item2a1cd6548b

http://www.ebay.com/itm/390422337315?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

 

Extra DIP8 Socket is needed to raise Headphones op-amp section, not required on RCA Buffer.

 

If you want, you can have the items sent to me, i can build it for you with 5% Silver Solder and ship it to ya for $5.
