I wonder if Jason have tried using Vali’s pentode tubes in the output stage. If so, how it was the performance.

Ouch! Maybe that was a stupid question. But I'm happy to see the new products and hope someday to able to build a system with them.   Thanks

Thank you, Ableza. But, if I'm not asking too much, which properties are changed? Gain, FR, distortion. Or just catches fire?

Jason,   Is it possible to use 6922 tubes with adaptors?

Does anybody know if there is a compatible subminiature tube? Thanks in advance

What about measuring Modi 2U and making a null test?

Hi,   A little late but thanks for everyone for answering my questions.

Hi,   Are the differences between tube and ss outputs similar to those you heard in GF Tube Dac 11?   Thanks

What about adding a tube buffered output in the higher end DAC models? So the user can choose ss or tube output.

Hi, Looks like Tyll will measure some amps. If there is no problem, mind you sending a Valhalla 2 with Lisst tubes? And if I'm not asking too much, develop a 6N6P Lisst for these measuments? In this case, Tyll would be able to compare a full ss amp, full tube, ss pre -> tube out, tube pre -> ss...

Hi,   Why not making a null test? And could you record any song with both?

Jason,   You said at the beginning of the book, your friend gave you a tube amplifier and using it with your AKG you began to realize part of the "tube magic". After these years, with measurements, listening, building amplifiers with different topologies, did you come to any conclusion about...

You can try feed your  ican with Vali signal if you want to put some tube flavor in your orthos.

I want to have an idea of the way this amp sounds because I live in Brazil and if I buy Vali, it's gonna take a long to arrive and shipping cost is a bit high in case I don't like it.

I know I asked that before but could someone, please, record a sample of song passing through Vali?   Thanks,

Maybe if they produce a tube preamp and a way to bypass it, so it could satisfy those who want a passive preamp and those who want a tube preamp with more inputs and outputs (my case).

Can somebody record a song passing through Vali and the original one to compare?

What I'm expecting from them is a preamp, maybe using Vali's topology (with more than two tubes) with a good amount of inputs and more than one output. This way that's gonna be one of the cheapest tube preamp in the market.

Jason,   Sorry for repeating my question:   "As an engineer, can you give your perspective about tube buffers? Something like using Vali's tubes for buffering the signal before Magni. Do you think the overall sound will change that much?   And what if you feed one amp with another one? Is...

Jason,   As an engineer, can you give your perspective about tube buffers? Something like using Vali's tubes for buffering the signal before Magni. Do you think the overall sound will change that much?   And what if you feed one amp with another one? Is the final sound a mix of them?  ...

What a relief analog'd,   I thought the topology was as it follows:   Digital: dac+buffer (tube) -> pre amp (ss) -> amp (ss) Analog: pre amp -> amp   But the correct is the one bellow, instead:   Digital: dac -> buffer (tube) -> pre amp (ss) -> amp (ss) Analog: buffer -> pre...

Reading again your review, project86, I noticed the TubeDAC only uses its tube when it's working as a dac, am I right?

Hi,   I have more questions, if you don't mind answering them.   For now, I don't know what I exactly want for the DT11, whether using in a speaker setup or headphone. Because of that, I'll try to cover both situations.   1) Considering a speaker setup, which amps do you recommend...

Hi all,   Can you recommend a dac/amp only as good as the dac/amp section on this one?   Thanks,   Eduardo

Hi,   Lemme see if I got after reading a lot: I need an amp if I want to use this one or the Yulong's sibling with speakers, do I?   Please, if you don't mind, answer the following questions. What's the difference between a combo dac/amp and a receiver? Is there any hifi dac/amp in this...
