Little Dot MK VI+ / VIII SE or Woo WA22

post #1 of 14
Thread Starter 

Which one is a better fit for high impedance headphones - Senns / Beyers?

 

Which ones are a better fit for low impedance headphones - Grados?

 

Which ones are a better fit for HE-500 / LCD2?

 

Does the Little Dot offer a better price per performance bargen?  

 

Is the Woo WA22 really 1K better then these Little Dots?

I received my Little Dot VI+ from David.

 

I will write a more formal review a bit later. This is the seventh vacumm tube amp I brought over the years and certainly can hold its own as compared to the Woo amps that I have listen to.

There is a thread somewhere where few people compared the BA and WA22 to the LD MKVI+ and I believed they preferred the LD. As a LD owner myself I am obviously biased but after six months of ownership I am still in awe of  this Chinese amp.

Have you had a chance to hear any Woo amp to compare?

 

Do you have the link to that thread as well?

 

Thanks.

I never heard a Woo amp myself. I couldn't find the exact thread but I am  pretty sure it was a report from a mini meet on this forum. Otherwise, you might find this thread helpful:

I am enjoying my Little Dot VI+. I did find that my amp is sensitive to what driver tube you are using. I am currently using RCA 6C8G tubes with adapters and the sound is wonderful and detailed. There is more stereo separation and a bigger sound field than I remember with the Woo WA5 amp. In some ways the Little Dot VI+ is a combination of the WA22 and most of the power of the WA5 while still an OTL amp.

I haven't heard any Little Dots, but I've put in ten hours on my WA22, and fronted by a vinyl front end, with Beyer T90's I have never heard better sound...

You have a balanced turntable? which one is that?

No. My phone preamp is single ended!

Which amp sounds more like the tubes you choose?

post #11 of 14

That is kind of a trick question to answer. All the models here are all tubes driven, no hybrids here. The LD's are OTL amps. The WA22 is a transformer coupled amp meaning that the power tubes just see the load from the transformer and the transformer drives the output. The LD four power tubes drives the output directly without using output caps meaning that the LD  is directly coupled to the outputs. While you do not have to, the WA22 requires balanced inputs to sound best and the LD requires balanced outputs devices to sound the very best. Another issue with the WA22 is that it uses a tube rectifier tube which can alter the sound a bit depending on the tube because of voltage drop. The LD uses SS rectification and has less voltage drop and more of a fixed level. The WA22 does not have pre-amp outputs as standard. . It is really the circuit design and the same with SS design on how the amp as a whole will sound.

Well, I guess my question should be.  Which one benefits more from tube rolling.  Or which one can I achieve a certain sound based on the tubes I choose.  I'm looking for that tubey sound.

You have either a tubey sound or a very analytical sounding amp depending on the tubes you are using. Various tube may behave different in different amps. I like my LD amp to be somewhat clear and an analytical sounding but have the spacious sound of tubes. Some may like a more "musical" sound amp. There is another thread from another user Baronbeehive for another opinion.

I think the WA22 will benefit more since it has more tubes to roll rectifier, driver and output.  Its hard for me to mix and match driver/output tubes on the MK6, I cant imagine adding another tube to experiment.
