This sounds like a real class act to me.
Another noob question ;)
Does the quality of the soldering in AMP's in general can determine the quality of the sound ? can you have interference or something because of bad soldering?
Or soldering its just like ON/OFF, Working/Not Working?
still have some concerns on the build up of the crack.
Does building the stock crack may have more expenses than the price of the kit it self (290$)?
Soldering might take some techniques. For example, temp cannot be too high, otherwise the iron might burn the board or wire.
The other thing i can think of is the choice of solder. Good solder can definitely improve the conductivity.
So for those who built up the BH Crack by yourselves, what solder do you guys recommend?
Congrats =) we have another HD650 diehard now it seems. Welcome!
Everyone was right. The HD650 sounds wonderful when run on a good amp. I had a chance to hear them on my home theater set up with my reference Denon receiver with a reference Pioneer Elite Bluray player and it sounded great! I think I would enjoy these for home use but not for on the go since it sounds like the Pure II amp will not drive it well enough to bother.
I wonder about the Portaphile 627X? Here are the spec's for this amp...does this amp have enough voltage?
Three Channel Design, Isolated Output Ground, Four Layer PCB, 3 x OPA627 , 6xBUF634′s, Jung Multiloop Topology, Powered by a Dual 3.7V Lithium Ion (Included, Rated for 500 Charges), Voltage Increased Internally to over 18Vpp, USB Adaptor/Charger Included (5V), Runs over 8-10 Hours on a full charge, Battery charges in about 7 Hours when Amplifier is charged while off, External Hi/Low Gain Switch (7/2), Small Size (2.75″ x 4″ x 1.12″), Elna Cerafine Caps, Instruction Sheet
Or the Portaphile MICRO?
Three Channel Design, Isolated Output Ground, Four Layer PCB, 3 x OPA627 (STANDARD) , 1XMUSES01 + 1×627 (OPTIONAL, 50.00 EXTRA) 6xBUF634′s, Jung Multiloop Topology, Powered by Single 3.7V Lithium Ion (Battery is rated for 500 Charges), Voltage Increased Internally to over 18Vpp, Power Adapter/Charger Included (5V), Runs 4 Hours on a full charge, Battery charges in 2.5 Hours when Amplifier is charged while off, External Hi/Low Gain Switch (OPA627 7/2, MUSES01 7/1.2), Small Size, Elna Cerafine Caps, Instruction Sheet
It would be great if either of these two amp would sound good for a HD650 portable set up, they are nice and small like the AK120 :)
I recall someone before mentioning one of the ALO portable amps working very well with the HD650. But TBH i think the HD650s are still more of a home solution... open cans just aren't ideal for on-the-go... unless you consider portable to be like you're staying at diff places all the time.
Most electrical solder, if it says rosin core; your good to go.
You can just ask someone to build it for you, or build it yourself which I thought was enjoyable. Some people just get antsy with upgraditus, and if you built the crack, you will know how to upgrade its components without having to buy another amp entirely. At first, I thought it was going to be a pain in my ass, but when you finish it and it works and music flows inside you Hallelujah . Ofcourse, YMMV keke
Thanks a lot, skeptic and smallmany. Good to hear that regular lead rosin core solder is sufficient. I am not too familiar with the soldering material, so my initial thought was "do i need to find some silver solder so that it might sound better"...lol
I find one YouTube clip from InnerFidelity, where Tyll briefly introduces how to build up the BH Crack: https://www.youtube.com/watch?v=s5rWCEux_BI
I agree. It would be weird to see someone out and about with 650's on. Not to mention people around you would hear your music almost as clearly as you did.
+1 on the cardas eutectic solder its a quality product and easy to use. One meters worth off of ebay will be plenty for a Crack+Speedball.
