With this combo, the headboard output is incredible! I'm not sure if the DAC output is all that good though. I may try reversing this combo to see if the DAC output will sound better and "hopefully" maintain the headphone output sound?

In which way isn't the line output that good? Is it too bright, maybe?


The LT1469 should be great also in the Dac. So surely you may try reversing the LTs you're using; or use the LT1469 in the Dac & one of the aforementioned LT1358, DY2000 and OPA2132 in the amp.

Btw, if the LT1364 is too bright the LT1358 should fix it.

I'll double check how it's doing in a little while. My impressions may have been "off" a little bit. I'm having a bad spell and medications can interfere some. But, on a side note, my MKV is making me smile bigtime!

Quick question:

It was suggested yesterday by penchum to replace the slee solo knob like i had done with the zero dac. It's something i have been thinking about for a while. The zero has been replaced with the chrome knob shown in the pic below. Do you think i should swap the solo to the same knob? Yes or no? I'm undecided. Its really not that important i guess, i just wouldn't mind some opinions.

Cheers



I don't think the pics really do them knob any justice at all. It gets warped by the lens.

Sorry I'm not into taking it apart. It sounds very good to me as is. I use HD650's with it and as a DAC for my Squeezebox.
Thanks, I was going to ask had any UK users been stung by HM Customs and Excise. I should have some money spare now to put towards some Sennheiser HD 650 / AKG K701's to use with the amp as well as my Livewires.

What a expensive find this site turned out to be

Ok i'm starting to notice big changes in the op amps i'm using. The LT1364 sounds great, but, it's not very forgiving with poorly recorded songs or bad quality songs such as mp3 or other lower format compressed songs. This doesn't really bother me as i'm using lossless, but for those using it from a computer, it may effect the sound.

I do love the opa 627 and the Lt1364 set up though.

Cheers for suggesting it Penchum.

I was wondering if anyone had heard anything from Lawrence regarding the batch that was supposed to come in early this week. I ordered from him last week, and he told me that he should get more in early this week, and ship soon thereafter. I sent him an email two days ago, and haven't heard from him, and was wondering if anyone else had any information. I need to head back to school soon, but it looks like I won't be getting it before then.

I like the new knob! One on each would really be attractive!!

Thanks! So do I. I'm also discovering the changes depending on the source quality. The original Opamp sounds pretty darn good with MP3's at 320, where the better Opamps are not that forgiving. Lossless Wavs sound great with the OPA627 + LT1364 combo. I figure, we need to find about 2 more combo's that sound great, identify which types of music they work best with and get that posted. Then it will be time to enjoy the changes!

Here is what I've tested so far: Note: "good" means only good. "great" means great. We recommend "great" for everyone.

Dac / Amp :

LT1057 + LT1469 DAC=good, phone=good

LT1057 + LT1364 DAC=good, phone=good

LT1057 + LT1361 DAC=good, phone=good

LT1057 + LM4562 DAC=good, phone=good

LT1361 + LT1469 DAC=good, phone=good

LT1361 + LT1364 DAC=good, phone=great

LT1361 + LT1057 DAC=good, phone=good

LT1361 + LM4562 DAC=good, phone=good

LT1364 + LT1469 DAC=great, phone=great

LT1364 + LT1361 DAC=great, phone=great

LT1364 + LT1057 DAC=great, phone=good

LT1364 + LM4562 DAC=great, phone=great

LT1469 + LT1364 DAC=good, phone =good

LT1469 + LT1361 DAC=great, phone=great

LT1469 + LT1057 DAC=great, phone=great

LT1469 + LM4562 DAC=great, phone=great

LM4562 + LT1469 DAC=good, phone=good

LM4562 + LT1364 DAC=good, phone=good

LM4562 + LT1361 DAC=good, phone=good

LM4562 + LT1057 DAC=good, phone=good

AD797 + LT1469 DAC=bright, phone=odd treble

AD797 + LT1364 DAC=bright, phone=odd treble

AD797 + LT1361 DAC=bright, phone=odd treble

AD797 + LT1057 DAC=bright, phone=odd treble

AD797 + LM4562 DAC=bright, phone=odd treble

OPA2604 + LT1469 DAC=good, phone=good

OPA2604 + LT1364 DAC=good, phone=good

OPA2604 + LT1361 DAC=good, phone=good

OPA2604 + LT1057 DAC=good, phone=good

OPA627s + LT1469 DAC=great, phone=good

OPA627s + LT1364 DAC=great, phone=great

OPA627s + LT1361 DAC=great, phone=great

OPA627s + LT1057 DAC=great, phone=good

OPA627s + LM4562 DAC=great, phone=great

LT1358 + LT1469 N/A

LT1469 + LT1358 N/A

LT1469 + OPA2132 N/A

DY2000 + LT1469 N/A

AD8599 + LT1361 N/A

LT1028 + LT1361 N/A

LT1028 + LT1358 N/A


N/A means I'm missing part of the combo to test it, so someone else can take a crack at it.
If you do any of the N/A's or have an addition, PM it too me and I'll add it. THX,

Well, If you do this right, then it will be a good reference tool for anyone who follows. At least, that is the hope!
