I have just began testing the first batch of amplifier boards for the upcoming 627X and the results have exceeded my expectations. I now expect to have the 627X available sooner than expected. I am looking at a three month wait time to those interested in taking advantage of the preorder discount. Preordering will close on 3/31/2013. Please see the products page for more details.
Pre-ordering the 627X
Excelent! I’ll do the pre-order as soon as I can.
Please put me on your pre-order mail list. Thanks.
Hi, will do and pre-ordering is now open!
How do I preorder? Also can I preorder and pay once my product is ready for shipping?
Cheers
To take advantage of the pre-order pricing you will need to pay before the pre-ordering end date of 3/31/2013. This is the allow me to take advantage of volume discounts when ordering parts. Think of it as a group buy where I’m passing the savings to the customer. Ship date is currently estimated to be mid to late May, hopefully sooner.
Thanks for the update. Is there any prototype, 3D rendering on how the new case is going to look like, any information on the specs (output impedance) that would be greatly appreciated.
No 3d rendering or specifications until I’m done with the final design. But, Output impedance should be similar to the current 627 which I measured to have an output impedance of .09 using a 10 ohm load and .7 using a 322 ohm load. I do have a prototype in the case I plan on using. No faceplates yet as I still need to make a few adjustments to accommodate the new potentiometer. Here’s the latest amplifier board with the new potentiometer but it’s not positioned correctly yet. Current Portaphile 627 on bottom, 627X in the middle and the HM-801 on top for size comparison.
I am solid, hopefully I have the fund ready in near future. It will be great if you can get active on head-fi, it makes communication a lot more easier.
Great news
I woud like to order one but just a question, does the 627x have better battery life? If yes how much?
Thank you
the 627 is rated at 4 hours and the newer 627x is rated at 8-10 hours
It’s also nice to have an 1/4 inch headphone out / perhaps a RCA in option
this may address those you like to use the portaphile as a desktop amp.
Thanks Kelvin, yes, the new 627X will have an estimate run time of 8-10 hours. I did consider the 1/4″ and RCA input options but unfortunately I can’t get them into the case without going larger. I am already hearing some feedback regarding the new size being more of a “transportable” amplifier instead of a truly portable amplifier so I would be concerned going to a larger size. So, no 1/4″ or RCA’s for the 627X at this.
Please place me on your pre order list for the 627X with all progress updates
Thanks

Hi Graham, I will get you on the notification list. Pre-ordering requires payment but can be done anytime until March 31st, the pre-ordering end date, to take advantage of the discounted pricing.

You can order the Portaphile 627X by going to the “Products” page, see link at top of page, and clicking on the 627X product. Then just follow the ordering process on that page. Please email me at the link at the top of the page if you have any questions or problems. Thanks!
Will the pot (TDK 2CP-601) be installed in pre-order items?
Yes, the TDK 2CP-601 will be standard on all 627X amplifiers including the pre-order discounted amplifiers.
If I don’t get it wrong…
Weight .40 kg
Dimensions 2.75 × 4.00 × 1.12 cm
The Dimensions should be in “inch” instead of “cm”??
I aimed to buy one of them. Did you aim to change some hardware specification except the battery? If the sound quality and a circuit still same as the thin one may be I will purchase the thin. 🙂
Hi Ceasar,
I’ve read that the 627x will require 7 hourse to a full charge.
That’s too long and will surely reduce the time I can enjoy your wonderfull amp.
So do you think about choosing another battery that could charge faster ?
Hi, the battery will charge fully between 6-7 hours when charged while the amplifier is OFF while charging. It’s a pretty large battery at over 4000mAh so the additional size requires a longer charge time.
Please add me to the pre-order list.

Hello Greg, getting on the pre-order list requires placing an order and submitting payment through the website.

Can you e-mail me directly? I logged in to order/pay and a couple of questions have come up. My e-mail address is ***.
Thanks.

I honestly think that there should be a bass booster via bass knob or switch. The 627 is nearly a perfect sounding amp. It definitely lacked bass and was laid back. If the 627x had a bass option like many portable amps do, It would certainly be a perfect unit in my opinion. Cheers
Hi Mathew, thank you for your feedback. I don’t have plans on implementing a variable bass boost feature on any of my amplifiers current or in the future. I am not a believer in artificially enhancing the original signal in any and this would include adding a bass boost knob.
Goddamn, great answer. Makes me want the 627x even more. A fantastic amp built by a man who doesn’t believe in artificial bass, I am sold :). Cheers Caesar
