Need help matching DAC to speakers and amp

You'll get no argument from me about being careful when dealing with an aluminium tweeter on a B&W speaker. You can even say that B&W tweeters made me the audiophile I am today. Just to note, you were very clear in your original post; your concern is very legitimate.

You are also right about something else. (And this is what really makes audio fun.) You state this:

"I know the price of a component is not the whole story.....but you will be hard pressed to convince me that price is not a good indicator of the quality of the equipment. Sure there are exceptions, and that's what makes them great buys.....but those are exceptions."

I disagree with that statement, but you are right. I would have a very hard time convincing you otherwise. Unfortunately, this is one of those things you will have to figure out yourself as you gain experience. One last comment: Just because you may pick a less expensive product does not, necessarily make it a good deal, or an exception. For example, if you get something for $3000 as opposed to $10000, the one for 3 is not, necessarily a good deal. Compared to similar products for $3000 it may be overpriced. That said, it just might be the right thing for you, that works in your system.

I just thought of 1 last thing that may help you out. You may, very well, make all good choices, set your system up, and still have an issue with your B&W tweeter. I just happened to come across a speaker cable made by Synergistic, called the Signature 10. Its a biwire cable that uses a different metal for the tweeter. Whatever it is, it works and is not that expensive. I really dislike making cable recommendations as a means to fix a problem and not just for signal transfer. Given the cost and how well it targets the problem, it makes more sense than buying new components. Also, I know it is no longer in production. You would either have to find one used or call Synergistic to ask what they currently make to replace it. Anyway, I hope this info helps you out.

I know exactly what you mean by your system being revealing. My B60 and Audio Physic Yara Evolution Bookshelves are ruthless of everything upstream. Even though they don't have metal tweeters, they still shine a light on any flaw, well, as much as anything can at this level of gear anyway.

Newer DACs only really have a couple advantages IMO...

1) Jitter reduction/reclocking
2) USB input and/or asynch USB
3) High-res capability

Those can equal better sound, but if your catalog is pretty much all redbook and you're not using a computer as a transport, they can be insignificant things IMO.

As I said in a previous post, there's no substitute for a good power supply and output stages. The entry level DACs pretty much all use wall-warts and op-amps. Both are pretty compromised IMO. Yeah, you can get a better power supply like the Pangea unit and/or roll op-amps, but why? Put that money towards a better DAC IMO.

When Bryston developed the BDA-1, James Tanner (VP of Bryston) said they were very surprised how little the DAC chip made. They said it made a difference, but no where near the difference that different power supplies, input stages and output stages made. That was in response to people asking why they used a Crystal chip rather than the flavor of the month ESS Sabre chip or others.

I own a 15+ year old Theta Cobalt DAC. It was their entry level DAC at the time, costing about $700 or so if I'm correct. I auditioned the MF V-DAC and DAC Magic in my system. They didn't hold a candle to the Theta. If DAC technology has come so far in the last 15 years, how come those DACs paled in comparison? The Theta has superior parts all around. It took $1k-ish DACs to get me to open up my wallet without reservation. I also heard the Benchmark and W4S DACs in my system, and the Rega DAC was an easy choice for me. The only sub $1k DAC that had a realistic chance was the Arcam rDAC. The Rega DAC was far better side by side, so no regrets.

Two DACs that get a lot of favorable press around here in the $1k range are the EE Minimax (whatever the current one is) and the Havana DAC. I heard the previous EE DAC, and it was very good. Not exactly my cup of tea, but very good nonetheless. Haven't heard the Havana DAC. From what I've read, I'm lead to believe the Havana and Rega are very similar.

If you want me to get more specific as to why I chose what I did or didn't choose the others, I'll elaborate.

My music library primarily comes from iTunes these days. Once I get a DAC worked out, and I am leaning towards the internal Bryston DAC since it eliminates a separate chassis and interconnects, I will work on how to get my music from iTunes to the DAC. Someone mentioned getting an older Apple TV box which keeps the library stored internally. Does anyone have any suggestions? My vision is to be able to access the library from an App on the iPhone or iPad and control it that way.

Hey, dumb question, does anyone know how the internal DAC is installed into the amp? Can do it myself?

I have the ATV Gen 1. Think of it as a 160 gb iPod with optical output. It also does YouTube and Internet radio. After owning it and using it for the last 2 years, I'll never go back to CDs again. The reason I went with it over a squeezebox (whichever one it was at the time) is that it has internal memory, thereby eliminating the need for a computer to be running. A NAS works the same way, but it's an extra piece and I'm horrible with setting up network stuff.

The ATV is limited to optical digital output (and analog RCA and HDMI). Some people see that as a downfall, but I don't. It doesn't do high-res, and you may run out of room due to the 160 gb not being a whole hell of a lot. My entire collection in Apple Lossless fits with a little room to spare. I'm guessing I have about 400 or so CDs synched to it. I have more CDs actually, but I didn't synch stuff that I never listen to.

I control mine with my iPhone 3GS. Works great. I actually like that better than the on screen display and my Harmony remote, as it's easier to find stuff.

Not sure how many ATV 1s are floating around nowadays.

I think Bryston may have to install the DAC card. Call them and ask, or even post over at the Bryston Circle at Audio Circle. James Tanner (Bryston VP) moderates the board and is a great guy to deal with.

The DAC I own, I consider to be a bit on the warm site the PS Audio Digital Link III. I think the sound and playback is incredible. I have coupled this with a SONOS setup playing out of my Ayre Integrate Amp (AX-7e). I have a NAS device with my computers that I host my iTunes (Apple Lossless) on, that presents the library to SONOS (control with great App on iPad, iPhone, etc.) I then have a digital coax from SONOS to the PS Audio DL III, from there I have XLR balanced connection to my Ayre. The sound is great and rivals my Ayre C-5xe (but that is my post in this forum). I would describe the sound as warmish, but just as detailed as the CD, and more powerful.
