You are right, of course. I just couldn't resist the commentary :D

Thank you sir. I have an excess of 12AU7's anyhow LOL. I've even started buying a few 6080 tubes from eBay in anticipation of a tube rolling frenzy :tongue_smile:

 

The only other quandry is the next DAC... I am unsure if I could really hear the improvement of a Bifrost Uber, over a Modi. That's not a negative commentary on the gear, it's simply the practical consequences of being an Old Guy with Old Ears. I am fairly sure I could hear the improvement in the amp. So the Crack isn't in question. But on the DAC, I'm just not sure I want to spend the money, if I can't hear the difference.

 

I am so puzzled about this that I am considering waiting for the next local meet, just to see if I can make a comparison somehow. I'd spend the money on the Bifrost, if I knew I could hear the difference. But I know my hearing cuts out after 14 kHz (based on sine wave test tones generated by Passmark SoundCheck, played on my best setup). So if my hearing is that limited, why spend the money? Buying a second Modi may be the best bet.

 

Curiously, I can still hear low frequencies quite well (20 Hz and slightly below).

Gosh I never want to lose my hearing frown.gif having damaged senses of any kind just terrifies me. I'm sorry about your lossUmustBkiddin

The AKG K701 series isn't really what I would call a high sensitivity headphone.

 

yeah i said it backwards. meant to say that this amp would be good for low sensitivity (AKG K701, planars, etc) and bad for high sensitivity (grado, denon, etc)

Dat 20Hz rumble on X10's... Hey It cut out at 10KHz for me, is it just my IEM?

How did you manage to measure one already? :eek:

In that case there would be no point in even considering tubes. Solid state always outperforms vacuum tubes at the same price point when it comes to strict technical accuracy. The appeal of tubes is that it "improves" the sound through euphonic distortions.

I was told that Apogee's DAC quality is excellent; would I hear a significant difference out of the 650s with certain other combos?

The Apogee is very good, the main complaint being that it's a bit on the harsh and bright side, but that makes it well suited to the HD650s which have laid back treble. It's very expensive just to use as a DAC+amp though, if you don't use it as an interface for recording music.

He brought his measuring rig to canjam obviously.  ;)

I get a little bit of a ground loop hum with my 840 Magni pairing, up to around 10 o'clock on the pot, and that hum is not evident on the 325s or even the 280s. I don't know if anyone else has experienced this.

FWIW,  this Isolation device

http://www.jkaudio.com/pureformer.htm

 

removed both ground loop hum and slight usb fuzz when placed in between my BiFrost Uber + Lyr!

 

another reviewer on amazon said it did the same for his Modi+Lyr combo.

YMMV

Probably depends on the metric and test conditions. Also note that one may build a class A tube and a class A SS. Then you have to consider hybrids, such as the Vali.

I'm 30 and can only hear to 12khz also... too many concerts, loud car system, loud headphones, and guns for quite a few years. One time I had to take a one hour UH60 helo ride with no hearing protection... I'm pretty sure that took it's toll as much as all of the long term stuff has.

post #374 of 4245

Ive been to my share of loud shows, have a loud car system, sub, amps, loud home system...  no guns tho.... but many shows with my ear smack up against a stack of 12 foot speakers. Id say my hearing is still good though... I listen more at moderate levels now... or at least i try too. ;)
