It's too bad that those 5 high school kids in 1971 couldn't have met at 3:20 PM so that these headphones would be $100 cheaper.

There are a number of inexpensive 6922 offerings. But I did find one for sale that cost far more than either version of the CTH. I think I can hold off on that one.

I ran music off an old iPod through the CTH for about 20-21 hours to burn-in the amp. I also am a rookie to the hobby (though fairly discerning in listening as I've played guitar since I was a kid) and this is my first real headphone amp, but I am impressed with the little listening that I've...

Congrats, Barzirker! Mine is due for delivery via USPS later this afternoon. By the way, if your workspace is too messy, I'll be embarrassed to post where I'm going to be initially using my CTH: it will be in our living room on a coffee table. Thanks for the impressions on the hardware.

That's really great that Alex is answering definitively! What a great source of information.

If you haven't already seen Tyll's review of the CTH at Inner Fidelity, it sounds like you should have humble expectations for tube rolling with the CTH. According to Tyll (and a few other reviews I've seen), the CTH seems to be optimized for the E-H 6922. Tyll stated that he tried several...

I almost ordered the original CTH but held off. Then Massdrop offered the CTH + SDAC version and I felt that it was a very good option for me, as I'm new to this headphone game and didn't have a standalone amp or DAC.

Thank you for the reply. I was mostly interested in trying the gold pin EH 6922, so that should be a safe swap to try.

Thanks, runeight. I know that many reviewers and even the designer are saying that tube-swapping really makes little impact. With that said, would there be any advantage to trying the gold pin version of the E-H 6922? Some reviews suggest a lower noise level, for instance.

I guess I'm fortunate in this instance. FedEx is saying "by end of day" on Saturday. I'm in the Midwest, so that probably helps given that the shipment originated in New Jersey, according to the FedEx website.

I'd be quite pleased to get my CTH on Saturday, That would give me a few days to try it out before I head back to work. Should be a lot of fun as this is the first higher-qualityl amp and DAC that I've purchased. I've been playing music off of a laptop or iPhone for the most part with my...

Same here. This is my first big-ticket purchase from Massdrop and I am looking forward to receiving it. I’m waiting for FedEx to generate an arrival for my CTH + SDAC.

Have you re-checked the cable connections? Similarly, have you tried a different cable to rule out a a bad or open connection somewhere in the cable itself? If the cable isn't at fault and the headphone is still under warranty, contact HiFiMan or perhaps the dealer you purchased the headphones...

What are your lingering concerns?

Thanks for the reply.
