REVIEW: Head-direct.com HiFiMan EF2 tube Hybrid Amp with USB DAC - Page 70

TOTALLY AGREE!!! But if you only ate rice and someone gave you mac & cheese that then be your favorite food EVER!!! See what im saying? The best part of tube stuff is the ability to roll and change or think of it this way each tube is a diffrent EQ setting so one may sound good with country while one sounds better with jazz. If i could roll OP-amps in digital solid state i would believe me but You did buy a GREAT tube so if your happy thats all that matters. if I could I would send you some old well NOS russian tubes I got on trade the other day when I guy brought in his preamp to trade on a new piece he also brought in his tubes I dont know why but I have I plethera of 5654,6ak5s 6ak7,s(dont use 6ak7 as they will work but sound HORRIBLE!!! very harsh and brite) and dont need them all just dont know what im going to do. I guess ill put them on ebay  after I test them all but I would just give them to some of you guys just so youll understand the whole art of tube rolling.Maybe someone wants to trade or has any idea what to do or how to get rid of them to let me know. OH have they even broke in yet??? about 100 hours is required and that means with signal going thru them not just powered on as the signal aligns the electrons during break in allowing the sound to become better so about 4 to 5 days of play. I will take a tuner or an i-pod or a cd player on repeat and let them break in the tubes like when im away or sleeping just an idea to try.Also cables make sure signal always travels the same way a rule of thumb is to use the writing on the said cable as a direction finder if it doesnt have arrows telling you so that once again the electrical signal makes one path way and in one direction Thats not my theroy thats KRELL CONRAD-JOHNSON MACINTOSH,s and most high end audio manufacturers will tell you thats why cables have directional arrows on them.I know like I said before "in the end EVERYTHING matters".

I only have around 20 hours on them, i've been playing music and watching movies with them. But i really like what i'm hearing. They're balanced while sounding warm. They work well with the warmness of the amp. When watching movies, certain audio details come out.

You can honestly tell me your hear these things?  I basically heard no difference between mullard, rca, and stock tubes.

LOL!!! Its OK man some people just dont hear any diffrence in fact I wish I didnt! Do you have any idea how much happier I would be If I didnt think "maybe this tube will sound or maybe this cable will sound....."every time I sat down to my rig.Sometimes I have to just enjoy not critique my rig and alot of us (audiophiles) get so caught up in looking for that"sound" that we"I" forget its all about the music so I really am envious of you!

Oh yeah and just wait untill we get into how some namebrand power cord sounds better than the stock power cord

Yes and basically think of tube rolling like op-amps they all have a signature sound but some people just dont hear it and thats fine if the other post I put up ever comes up youll see how I am really jealous I wish I didnt hear the diffrence!

when compared to the stock tubes, yes. Certain details, came out more, i would think the treble was just more apparent with the mullards than stock when i watched movies

Will these be able to drive a AKG 701/702 fairly well ?

Say what you want about driving headphones well, but for 7 months I used the EF2 and I was never able to tell a difference between it and an ipod with my HD580.  I used mullard tubes also.

Thanks Headphone addict for the info .  @ Crazy Carl  , Did you feel the same with any other headphones as well ?

Ultrasone HFI-580.

I believe that Crazy Carl can't tell the difference.

But I also agree that most people can tell the difference

I can voice my opinion to new posts, as you guys do also.
