I picked up a used LD I+ today, locally.  Still has the stock tubes and stock op-amp chip.  However, I plugged my Squeezebox (Burr-Brown DAC) into the amp and used my HifiMAN HE-400s with it.  The sound was excellent!   I don't have much of a hybrid amp background to compare it to, but I did have the HifiMAN EF-2A for a few months.  However, I fed it a signal from an iPod, which I realize now wasn't good at all.  I would have loved to hear the EF-2A with the Squeezebox.  However, I now need to lift the cover and check the position of the gain.  I'm running it at about 10 O'clock and the volume seems at a good level for me.
 
More to follow as I read through this thread a bit more and look into some op-amp options.

Nice...sounds like a great pairing!

Marts, My LDI+ was doing something similar. It would cut the right channel and no matter what I plugged them into it wouldn't come back.
 
UNTIL, I decided to get desperate and plug them into my iPhone, my case prevented me from plugging them in all the way and I got a faint little buzz, and then all of a sudden the right channel came back, I don't know if that could work for yours, but apparently my iPhone is magic.
 
I'd also like to add that this has only happened twice, and both times the amp was on for longer than 12 hours straight, so that could have also been a cause, don't know about your case.

yeah you should not leave your amp on for that long at all.

the LD, IMHO and limited opinion, seems to be one of the best bargains in the audiophile world. just a humble opinion of yours truly.

When I saw the build quality I was getting for such a cheap price, I was pretty floored. For budget audio, it's a no-brainer...especially for those who want to play around with tubes. All I did was upgrade to some $50 Telefunkens and my LD amp sounds fantastic. 

 

[spiderking31]

Why would you not buy the mk3??

 

[spiderking31]

Your amp might be defective....

I hear ya!!!  I have had both of mine for several years and love 'em with low impedance cans.  Three families of tubes, op-amp rolling, price, customer service etc......
 
Winner indeed..
 
Cheers

 

[Melvins]

your reviews and respect for it really motivated me to get it lol. indirectly of course, through what you said on the forums. 

 

[HeatFan12]

lol...Thanks Melvins...
 
I love this little amp...So much fun...I have one with the stock op-amp with EF91, EF92 tubes and the other with LT1364 op-amp with 408A tubes...Fun Fun Fun...
 
Cheers

Yep, the customer service is fantastic. David is available via email and extrememly helpful throughout the entire process. I will definitley buy from him again...no question. 
 
I'm really glad to know that yours are still up and running strong after several years...that doesn't surprise me in the least, though, given the quality of parts he uses. The thing is built like a tank!  I can't believe he doesn't charge more than what he does....but I'm glad he doesn't lol.

Love seeing those beautiful RS-1s sitting next to the LD

I'm looking to spend about 60-70 dollars on tubes for this thing. I'm looking for two sets with different sound signatures or ones that specifically compliment my phones. I have AKG K702, Denon D2000 and grado sr80i. Which 2 of these 5 would you choose and what do they sound like? Are there any others you'd recommend?
