Sorry to hear that man.. I didn't get the F bombs but it must have been frustrating on top of the issues you are dealing with. Wish I had done research on these guys before going through with it. I hope you don't ever receive a faulty product from them. As mentioned above. If the product...

I agree with you. If nothing was wrong it'll have been a good experience. That's what separates the good from the bad, though. The ability to count on them when **** doesn't go according to plan. No one wants to receive a faulty one but when it occurs good sellers don't try to cheat folks. I've...

Wow. Wish I saw those reports earlier. I put in the gist of the conversation here. I just browsed through their feedback and they basically swore at another buyer. Anyways just don't buy from hot fi. Not worth your troubles. https://m.imgur.com/4U35LV9,RcONFr1,P3HfbzU

Not this one. He's laughing in his reply to me now because he got away with it. He intended to trick me and waited for the protection period to go out. I buy on AliExpress alot so not all of them are bad which is why I didn't think I would get tricked in resolution. Lesson learnt make sure you...

What happened was the cable of the iem I received was faulty. The mmcx connection is dodgy so I lose sound every now and then. I applied for a partial dispute to buy replacement connectors but he said he would send me a replacement cable so I would cancel the dispute. From there he gave a...

Sharing another seller on AliExpress to avoid. Do not buy from Hotfi earphone and headphone. He gave a fake tracking code until the protection time had run out. Disappointing the way these guys operate.

  May not exactly be your point but I've found the 007s need to hit a certain volume to really be foot tapping. While on the Lambdas... I do think the SR-202s is THE value buy. It is wonderful in making music - I haven't found the newer models to better really. It hardly gets any head time...

  Okay... I just wanted to address the tube vs ss generalization, that's all. :) For my Mk1... moving from the KGSSHV to the megatron, the big change for me was how holographic and involving the tube amp was, and that gain is offset by losing a bit of the bass "slam" that I got used to from the...

  I'd be careful with generalizations like that. Tubes (well designed and executed) don't automatically mean a warm sound. From my experience, the stuff that comes out of Kevin's schematics definitely don't steer that way.

  Pot calling the kettle black much?   Funny, all I see is you proclaiming anything sold in that French forum as being the absolute best for Stax headphones - and you've admitted to only listening to a few Stax amps, Electra and the RKV. So you're still going to insist that the newly...

  It's been awhile since I heard the 507 or 009 (both on normal Stax amps), but I seem to recall fairly significant differences in sound stage. What music/files are you listening to?   If you can't appreciate the difference I'm sure your wallet would be happy (and thankful!) :)

  I'm starting to get it wink (no pun intended )    I won't block him... I just won't respond... I'll just have to trust myself with that 

Ok I don't intend to get into a discussion with someone who isn't listening.   So far, you've just proven everything that I've said. You're doing things zealously and with a DMM and a microphone (have you seen the stuff arnaud models with a simulated head/listening test environment?). Really...

  I guess you don't get the point I was trying to make on pro bono. Anyways I've said my piece. Carry on doing what you want to do.   In terms of measurements... for amplifiers it's mainly to do with a scope... or something that lets you chart out freq response effectively. I don't think I've...

  Well... look at it this way. If you think something is good you want it to do well. What do you think is happening with the way you're approaching this now? Don't you see that you're potentially harming RKV more than you're helping it?   You're basically yelling at a group of folks who have...

I think why everyone is tiring is because you're continually pushing RKV stuff... It's like you're working for them?

Lots of funny stuff in just the last few posts. Funny how everyone trying to correct everyone isn't really clear themselves or understand sarcasm...

  I agree... you described them really well but just thought I made that distinction clearer in the context of the question "offboard vs onboard" that's all :)   There are also newer variants of the KGSSHV design - KG and Spritzer have been continually working on this to keep sourcing of...

You can use either parts and build for offboard or onboard builds.. the only thing is the Sanyo can only take up to 450V supplies. In context of the KGSSHV, offboard just means the transistors on the amp boards have heat dissipating through the larger offboard heatsinks, while with the onboard...

  Thanks for the quick reply darin - your contribution to this thread cannot be understated.   I'll try to find some time to test this out this coming weekend, too. 

Hi Hekeli,   Thanks for the great info! Just wondering, are using your own custom HPEQ and PRIR for it? I'm asking because I thought it may be interesting to use this to compare amps/headphone combos... but wouldn't the custom EQs override most of the differences?   Quote:

  Doesn't matter which version of the PSU board. The tubes draw about 2-3 times more than the KGSSHV - which is why you need to remove the current limiters for the Mosfets. It'll work with the onboard sinks - it just eats the LT1021s for me when cased up cause of the heat (and I use it in an...

  IMO just focus on the Megatron... apart from sounding better, you'd probably get it up faster because there're a lot less parts to worry about. Additionally, do go offboard for the PS instead of the onboard sinks (I would recommend this as it can get quite hot in Oz, too).   If you do buy...

Please do share your impressions of the two amps. Very interested to learn more about the Chinese DIY amp, too :)

Since you're comfortable with DIY... For around that amount and if you're going to go with SMD anyways, I'd propose going with something like this: http://www.8thnote.eu/ or Joshua Tree?.   I'm using this in my latest amp and it's better than the shunt 24-step attenuators I used to make for...
