Even for Something like even a godap x is a huge leap over and imod, which is why there aren't many post about them anymore. But if rockbox is a must, then the imod is the best route since rockbox doesn't work with idevice dacs. I was a long time lover of rockbox myself, but the first time I listened to an idevice dac, the improvement was more than enough for me to forget about rockbox. But ymmv.

Getting humorous now, it seems like every time I go down road A, there is someone right around the corner that says A sucks and that I should have done B. It never ends, I just want to have a great sounding portable setup.

So, does 5.5g redwine iMod with P51 mustang suck now that there are so many new gadgets out there? I know, I should DiY to save money and/or use a portable DAC, etc, etc, but bit the bullet and bought the iMod after reading hundreds of hype posts. I do have an iPhone 4...so if I use that with a Godap x it will be a "huge leap over an iMod", and "obliterate" it as you say? Budget is not a huge factor for me. Can anyone recommend a great portable setup, or are they all "ymmv"? My head is swimming with the countless posts of dacs, daps, amps, lods, phones, it goes on forever.

I realize there is a huge factor of subjectiveness with this stuff, but moodyrn, you do seem to have a very strong opinion about what I have done. If you were to spend a few grand on great closed portable phones with a great sounding sound source/amp, how bad did I screw up in your opinion? (BTW, returning the ATH W5000's because they creak). Should I throw away the iMod and RSA amp as you seem to suggest and start from scratch down a completely different road with respectable components that are not in the category of suck and as you say, "there aren't many posts about them anymore"? I'm not 100% tied to Rockbox, I just like that is bypasses iTunes and that it supports flac. I'm reading now about how "good" some ppl think the Fostex HP P1 is as an amp and DAC, could use my iPhone with lossless files with it and convince Vinny and Ray to let me return my iMod and p51? How would I bypass the internal DAC on the iPhone 4, just use an LOD to the Fostex?

Edit: it appears many ppl use the Fostex as a DAC only and use and RSA as an amp. Are the RSA amps better than the amp in the hp p1? I would prefer to only have 2 modules to carry around for portable sound. If the iMod totally gets obliterated, as you say, compared to newer dacs, I may have to consider a switch. Does it really rise to a level of obliteration?

I don't think you screwed up. Before the days of portable idevice dac, the imod was your only option if you wanted to get good sound out of you ipod into a good quality amp. But now there are better options for around the same price. It's like buying a three year old computer for the price of what a new one would cost that will have more memory, faster cpu, better graphics etc.

But it also depends on what you want. If rockbox is a high priority, and you value the smallest size setup over having the best sounding setup, then the imod still makes a lot of sense. As for portable dacs for a 6g or newer ipod or idevice, then there's numerous possibilies out there now. You have the godap x as mention previously, vamp versa, few different versions of the clas, the fostex hp p1, and even sony has come out with an all in one idevice dac, amp combo. What many people, including myself is waiting on, is the upcoming hifi m8 which is suppose to be a real game changer. There's a huge thread on it here on headfi. All of these things now render the imod obsolete, but the imod still have a place considering what you are looking for with your portable setup.

Understood that there is always newer tech coming out. Regarding my questions, are the amps in these combos you mentioned better than RSA amps? If not, does the DAC upgrade from the ipod Wolf trump the amp downgrade? ...Do I need to stack an external dac on top of an amp to make up for the sub par amp? don't care too much about Rockbox, as I said. Don't really need it.

Size is not the biggest factor, just need to fit it in my briefcase, really. If you had a p51 amp, an iPod 5g, an iMod 5.5g, an iPhone 4, and an ipad mini, what would you do? Would like closed phones for decent isolation on the bus.

iPhone 4, bypassing the DAC (how?) HP P1 for the DAC -> p51 amp -> ATH?

The above example assumes the DAC upgrade includes a crappy amp, requiring a separate hq amp component. At least that is what people seem to do on other threads I have read. Looking for good recommendations, thanks.

Well, the rsa balanced portable amp is better than most of the amps in the combos. But some of the combos have amps good enough when paired with the included dac will surpass the imod/rsa amp combo. But for me, just upgrading the dac alone is worth it. As they say when it comes to dacs, "garbage in garbage out. So it really depends on who you ask. I would prefer even something like the godap x or vamp versa to the imod/rsa combo provided the cans you have aren't too hard to drive. Neither of the combos will have an amp as powerful as the rsa when it comes to hard to driving cans. The one exception is the upcoming hifi m8. It will have a dac as good as a stand alone desktop dac as well as an included amp that's suppose to be even better than the rsa amps, and you can also use it as a usb dac/amp combo for your computer since it also will have a pc usb input.. But again, that's what's being reported. But the amp part of that is going to provide 1500mw of power and it's balanced as well.

But you can still have your cake and eat it too if you wanted to still use the rsa amp since the clas is a stand alone dac without an included amp. So you can use that in combination with your rsa amp. The fostex hp p1 will let you bypass it's internal amp just use the dac part to pair with your rsa amp as well. So you have many options and they all will still be portable as well while giving you a much cleaner sounding source.

So, to answer my question, ditch the iMod and use an external DAC with which of the iPods in my list, and how to bypass the internal DAC in the I device, I'm assuming the iPhone 4? Not sure how to bypass my iphone dac. Why not use the iPod 5g and an external DAC while we are bypassing the iPod DAC regardless?
Anyone have any other thoughts?
Would be nice to do a DAC amp combo without sacrificing the amp, so I can drive nice phones and have it sound great. You are saying that sacrificing the amp would be an improvement because of the DAC, correct? (So long as the phones are just right for the weak amp)

Does anyone have measurement specs for the imod 5.5 and unmodded 5.5?

With either the clas or the fostex, you don't have to sacrifice your amp. You can use the dac only and run the lineout from the dac in the clas or fostex to your amp. With the godap or vamp, you would have to use their internal amp. But not with the clas or fostex. And if you'll willing to wait for the hifi m8, which is only a month or two away from production, it's included amp is at least on par with the rsa amp. It's being reported to be better, but only time will tell on that. You already have the imod, if you like the way it sounds, keep it and be happy.

uchihaitachi, I will measure my 5.5 imod and let you know the exact dimensions. I don't have an unmodded 5.5, to measure, sorry.

 

Moodyrn, thanks for the info. Do you know how I would bypass the DAC on the iPhone 4 and run sound into the Fostex DAC or the m8 (when it comes out) instead? You say the newer idevices are better for running into an external DAC, but what does it matter how old the device is if you are bypassing the DAC regardless? That was my question, and if you don't have an answer, that is cool, just say so. Thanks for any advice.

By dimensions I don't mean the literal size. I was referring to the frequency response lol but thanks anyway! 

 

I don't think you can bypass the DAC of any apple products. Yes you can bypass the amp through the LOD but no the DAC to my knowledge.

Thanks. BTW, I asked Vinnie for the same data on the iMod, and he did not have it.

Reading all about the hifi m8, it apparently bypasses the DAC on iPhones, right? Or maybe it takes the data after the DAC on the phone and runs it through the m8 DAC, but I would not see the point of using 2 dacs. Last week I spent $1000 on an iMod and RSA amp. Guess I should have waited, but had no clue this was about to come out. HUGE oops. But hey, the iMod and RSA should sound pretty darn good regardless.
post #72 of 82
No, it completely bypasses the internal dac in the iphone just like every other product I've told you about. I think you are very confuse about the whole idevice dac thing. Not just any dac will bypass the internal dac of an ipod or iphone. The only ones that does it are the products I've listed as being idevice compatible. So that doesn't include the 5.5g ipod, but does include every ipod made after it(example: 6g, 7g) and also most of the iphones and ipod touches. With the idevice compatible dacs, you don't need anything else to pair them with to bypass the internal dac. All you do it plug one end into the iphone/ipod dock connector and the other end into the usb connector on the device.

You are incorrect. There are several product that bypasses the internal dac of apple products. There are both desktop versions and portable versions that does this. Infact many of them have been out for a few years now, and there are numerous threads about each one. I can't believe you are that far behind in the times. Here's a couple of links on a couple of them.

http://cypherlabs.com/

http://www.fostexinternational.com/docs/products/HP-P1.shtml

Both of those are portable, and here's a link to a desktop one that's only 99.00

Lossless.  Plenty of space on the 4G and 5.5.

Yeah, I agree. With mp3s, it'll be hard to notice a difference between a stock ipod, and an imod.
