Question about Little Dot II+

Thread Starter 
Hi,

I'm getting an LCD for my room and was thinking about getting a Little Dot II+ amp to connect with my LCD and Audio Techinca ATH-A900. Would this be a good move? Would I need to purchase anything else? I've never had an amplifier before so I don't know that much about this sort of stuff. I also will be getting a PS3 if this helps.

Thanks.

don't buy a LD2+. it's has a faulty design which causes the tubes to arc. in time, the amp will die and may take some of your equipment with it.

now the LD2++ is totally different. that is an amp i can strongly recommend. have used it a lot. sounds very good. excellent amp for the money. am selling mine now (see sig). don't need it anymore now that i have moved up the chain.

but to summarize, LD2+ = bad; LD2++ = good.

LOL, you trying to get him to buy your LD2++ vcoheda?

Seriously though, the LD2+ is fine overall and most who have heard both the + and ++ would say the + is the better sounding. Now, vcoheda is somewhat correct that many did have the tube arcing problem. But not all. Even with the ones that had the arcing problem, only a handful had the problem of dieing and taking other equipment with them. Main thing to remember with the LD2+ is to power up without headphones plugged in then plug them in soon after powering up.

well. he said he was interested in a LD. buying used is always cheaper than buying new. when the stars align, you should point it out. also, the arcing issue of the LD2+ is not minor. i would not buy one and would not recommend one to others. i think it would be a mistake.

The LDII+ is a fine sounding amp for what they cost. Directly heated triodes have a sweetness that defies words. The older chinese tubes are very poor on quality control and some arc intermally. If you can find the Russian tubes, the problem is solved. I have several II+'s and bought a number of tubes sometime ago and culled them and threw away about 1/4 of 'em and have NO arcing problem. Check ebay regularly for the Russian 4P1S equiv.- 4P1N, 4P1L tubes and eventually they turn up The input tubes are readily available and cheap. 50year old tube design is not astrophysics. The amp is a very straight forward simplistic design that can last many years.

Ste05 "was" contemplating about getting my LD II+ on e*ay but i guess all this arcing business would put pay to that.

Gee... i've been missing out on this arcing show on my amp.

hahaha, half-time score:

vcoheda - 1
jaspert - 0

I have no problem with my LDII+ either - I love that little bugger too. I bought it when it was the current model and highly recommend it, however common sense would suggest looking at the ++ model now as it has more tube-rolling options, and it doesn't have any history of arcing problems. Having said that, I don't think ste05 should shy away from buying yours if the price is right, as you can attest to the fact that it doesn't have the arcing problem and it would make a good first amp.

I'll probably never sell my LDII+ as it's good fun and has a nice euphonic presentation for when you just want to kick back.

I can't comment on how the LDII+ partners with the ATH-A900's as I haven't heard them together.

i am very surprised. you are saying that your LD2+ has never arced. you have never seen a bright flash of light from either power tube when turning the unit on - ever. i'm sorry but i find that hard to believe. when the issue arose with the LD2+, there were various statements made by Mr. Yang to the effect that the design was not 100 percent compatible with the power tubes and that is what caused the arcing. there is no arcing with the LD2++ because it uses a different and wholly compatible power tube.

well I was using different power tubes from the start, so that's probably why I never saw arcing?

Hmm, I don't use stock power tubes either... was the problem caused by the unit or the tubes? If it was the tubes, then there's nothing wrong with the LDII+ per se, but rather the original power tubes.

Since Jaspert doesn't have the problem either, then maybe David shipped his out with better specified tubes?
