Quote: Yes, I just have to remember I have three volume switches. It sounded excellent today. Thanks

Quote: I also noticed when I went into my music server the volume was turned all the way up so I turned that down to about 70%. So far it's much better. Thanks

Quote: Yes I do mean the gain switch on the O2 I have it pushed in, is that correct with the HD650? The O2 instructions said to turn up the volume on source to 60-80%. I tried it at 50% on the Mac Book and turned the volume up on the O2, is that what your suggesting?  So far it's better, I...

Hi ClieOS   Just received my O2 this afternoon and the amp appears wonderful. But I do have some questions. When using my Mog music service 320Kbps and the HD650 some songs seem to have so much bass as if to a point of distortion. I pressed in on the button of the O2 which I guess is higher...

Quote: Thank you

Quote: Ok thats good to know. I was also thinking of the little dot 1 plus but their site said it's not for high impedance HP's there fore my thoughts moved to the O2. Thanks

Quote:  I started to look at your top pick the O2 will that pair well with HD650? I started to order the Little Dot MK1 plus but they said not to pair it with high impedance HP. Also the Jds site said the O2 is good up to 250 Ohms so I just wanted to clear these issues up.Thanks

Can some tell me if the T1 works with the MacBook/HD650. I want to use the tube amp and Dac, I don't get the Tube Dac and USB connections problem. Thanks

Quote: I meant reliability in general not in particular one company, just saying it's an important consideration.

Quote: If your not sure the G3 will be a nice difference, I will just hold I that one. I heard the MM combo is nice but it would have to be worth over the e11 but if you have not tried it I can wait, I believe like you, others like it a lot. The IFI audio is not easy to find. Also...

Quote: I can keep the E11 for a portable if it's not a big difference from the E17. The E11's sound great to me or it's more the HD650. The E11 does come loose a little from the MacBook just got to push it back in. Will a 150.00 to 225.00 budget for a tube amp make a big difference and will...

Quote: Hi ClieOS and Evshrug,   Just thought I should report back on my experience, I received my HD 650 today. The Head Flier web site is moving me along quickly. So far I using my 2009 Mac Book with Mog music service mostly, with 320Kbps and my E11. I'm getting good sound volume from...

Quote: Hi I used the E11 today with the GR07 and it was a nice improvement. It's like what you said about amps it took out the swings and gave a nice and steady strong flow. I spoke with my son today and I may give him the E11 instead of paying the charges fro a return and since it's so...

Quote: I have had more discussions on Head Fi then any other site I have ever been on. I used to play music when I was in High School and at that time I felt it was very calming. After HS I was just too involved with work to play music. Just a comment on maybe what type of personalities who...

Quote: Okay I got my feet wet and opened up the E11. My first impression as this is my first Amp, overall sound improved with the Mac Book and the A900x, it sounds fuller and richer I enjoy the SQ more. The USB charge as u know doesn't work at the same time your listening.  Then I tried...

Quote: Yes I do listen in lower volume your very thoughtful. It's amazing how you can detail your thoughts on all these variations, of so much equipment.!

Quote: That's a very nice offer but I live in Monterey, CA. Wow you gave me a lot of information that's very nice of you. My first thought when I started looking into powering the HD 650 was the E12 a lot of attention was on the E12 because it was new and powerful so it caught my attention...

Quote: I have a question on the E12 sounds like a great amp but now what do u do for a Dac? 

Quote: Sounds like a nice trip lucky you. Please fill me in when you can. Thanks

Quote: I think I understand. I had the HD598 for a week using it mostly on my Mac Book un amped and I think I felt some swings, for a while it felt full and rich in sound and then it didn't. So I guess a good amp would fill that void. Is that what your saying? My A900x feels very good most...

Quote: I looked at the Fii0 site and it said it runs HP's up to 150ohm, Amazon said up to 300ohms and Micca said up to 600ohms. You got to love it.

Quote: Okay you surprised me with the E17 Amp/Dac suggestion, I guess you mean the stand alone E17 not with the E9. You had me looking for desk tops without one of your shoot outs which was difficult. I enjoy the shootouts that is to say keep up the good work. I was thinking the Schilt...

Quote: Funny that you said how good the HD600 sounds with the Mac Book. I have on order a refurbished HD650 and I'm working on deciding on a combo for the HD650. But I'm wondering just how good the Macbook is so at least its a great source. Thanks

Quote: Yes I was thinking the same thing about the E9 combo I know it can be had for a good price. But like you said it may not stand up SQ wise and the reliability maybe a problem but it would kill two birds with one stone. I heard their maybe newer versions. I still think your right about...
