It isn't that simple. For one thing, good irons are expensive - and they'll get fierce competition from other Chinese companies which made some really good sounding stuff (and in large quantity so they already got a price advantage, not to mention exposure to the market).

It would cost a lot more to built tube speakers amps and the shipping costs for delivery from China will be very high. What many people do is to use the Little Dots as a pre-amp to a SS amp or in my case to an active powered speakers in addition to headphones. My airmotiv 6 monitors have 110 RMS watts for the woofer and 100 watts RMS for the tweeter. You will be somewhat limited in choices to speakers that have high efficiency for tube speaker amps. For example I have  pair of QuickSIlver M135 mono tube amps which will equal in power to the built in amps of my Emotiva Airmotiv6 but they weight about 70lb each. Like the pervious poster, good irons are expensive.

I finally received my mk6+ and I have a couple of questions for any existing owners,I've had to temporarily connect it to my dac (Yulong D18) with a single ended cable,I'm waiting for some longer XLR cables to arrive.The 4 pin XLR on the front only seems to work when I plug another pair of headphones into the rear 6.3mm jack socket,is this because I'm using the rca's to connect the amp or is there a fault?Also I have had to turn the volume upto between 80 &90 just to hear it and that's on both front XLR & rear jack socket.I must admit I haven't checked the gain settings yet,I don't know what the amp comes set to.The headphones im using are a balanced hd650 and a momentum at the moment.
I hope this isn't faulty I don't want to have to send this back to China.

If you have to turn up the volume to 80 to 90 for the HD650 you do have a fault. Originally the LD VI was for balanced mode only and they added the single ended inputs later on which makes it the + version. I am using the balanced inputs from my source and the balanced outputs on the back to my monitors. The front balanced still works fine for my balanced headphones and the 6.3 on the rear works fine also. I would wait until you get the balanced cables and see if that is going to fix the issue. I have not fully tested the single ended inputs on my LD for balanced outputs on the front.  Does the right meter turns on after three minutes?  I am assuming that you are using the Yulong D18 at full output.

Thanks john57 I'll wait until I get my balanced cables before I do anything drastic,yes the right meter switches on after about 3 minutes.What did you mean by "using the d18 at full output" I didn't think the output was adjustable.

You are right I check the D18 manual and it states:

 

***Notice: Both of the RCA and XLR line level outputs are NOT controlled by the Volume, and it is always in full output
level. Any equipment connected to these outputs must has a proper volume control, otherwise it might be
damaged. It might harm the hearing of audience too. We are not responsible for any kind of such results.

Ah I thought it was,you had me worried for a minute.
I've just checked on the amp(I had it running to burn it in )and it appears that the right channel has died,the meter has dropped to 40 from 80 and also 1 of the power tubes doesn't appear to be glowing as brightly as the others,it seems that there will be a trip to china in this amps future,dammit!

So I'm totally new to the tube amp scene, and balanced headphones as well; and decided to make a decent first step to see what all the fuss is about.

 

Ordered LD MK VIII SE with the LD Dac I and cans from Moon Audio with his specialty cable, Senh HD650-With 5' Silver Dragon V3 Headphone Cable-Neutrik Gold Plated 4pin Male XLR

 

Wondering if any MK VIII SE owners who've used hd650's which tubes were best for them?

 

Also wondering if any good reading for do's n don'ts when it comes to tube amps.

 

Regards, Mike.

The most important thing is absolutely do not replace/pull out tubes while the amp is still on. Also do not plug/unplug headphone while the amp is still on.

Some clarification in regards to the tube types needed for the MK8 would be nice; 4 power and 2 that the sound goes through I'm guessing?

 

Reading all these posts and people say these are great but not sure if I need 2 or 4, and what about spares, or matched pairs how important it is?

 

 

I'm just gonna list off some tubes and if someone could shed some light on the subject it would be much appreciated!

 

TUNG-SOL-6AS7G 5998 ECC230

 

6SL7GT / VT-229

 

Tesla E83CC/ECC803S/12ax7

 

RCA 6AS7G and RCA 5691

 

Guess what I'm really asking is what are the cream of the crop for this amp?

 

Regards, Mike.

post #581 of 1385

You can't use those Octal preamp tubes (6sn7/5998/6SL7) with the Mk8. The 8 uses 4x 6h30 and 2x 12AT7 tube. Generally speaking, the sound of tubes depends on the circuit they're put in. There's no guarantee that one tube that is nice with one amp, will sound nice with other.

 

The most revered 6h30 tube is the "supertube" (6h30P-DR) - they're really expensive these days though. Just try to play with cheaper tubes first.

 

12AT7 there's a whole family of these tubes (12ax7/12at7/12bh7/12au7/5814 etc etc) some got higher gain, some got lower gain. Usually, it's ok to replace a tube of the family with a lower/same gain variant but you should still check with David about which one is safe.

I would say do not plug in the headphones until after the amp has warm up and right meter is showing okay.

Sorry that you are having problems and yes you need to work with the vendor to resolve your issue.

Thanks,I will once I've received my XLR cables and doule checked exactly what's wrong with my amp,the cables seem to have been delayed in the post.
post #585 of 1385

Well I think I got the cream of the crop on their way... just ordered matched pairs 6N30P-DR 6H30 Pi SUPER TUBES 1979 REFLECTOR and SIEMENS ECC801S 12AT7 E81CC matched pair.

 

Tingling with excitement to see the difference.
