I could not read the entire thread, so good on ya Jim2. I tried to search for core power Technologies and either they are no longer in business or were sold and not coming up with a google search for core power technologies.com...
Has anyone tried these stunning new CPT power cord?
Considering the many, many brands of power cords I've tried in my very well accomplished high-end system, I have never been so impacted by these Core Power Technology power cords. Within a very short period(15-20) minutes my system literally came alive. Soundstage opened wider and deeper. The background became dead silent, space between instruments and stage members were more focused and everything sounded cleaner and musical than ever. My highs had a glorious crispness and symbols shimmered. Midrange through my 2" horn became more dynamic and punchy. My 15" bass driver tightened and dug low with great control. My Rel G1 which is a fabulous sub on its own but with a CPT 150 on it is another story. Running high pass from my sub to my Audiozen Noah amplifier, music depth is just stunning. Lower end bass is authoritative and clean with solid grip and impact.
My experience with these power cords is truly magical. The scary part of the above is I only have one 150 on my sub and one 300 from my wall to my 6 outlet bar. I still need 3 more to complete my system. I could just imagine the level after that...In closing, I cannot emphasize enough to try one of these in your system. I CANNOT and WIIL NOT take these out as they are that good. But hold your jaw, cuz what you've been listening to will just become real after Core Power Technologies.
Cheers....and let the tapping begin.......

I've scrolled thru this entire thread. Recently, my wife and I finally finished watching Breaking Bad. We're both disappointed that it's over. She's actually complaining about it. I may have her start reading this thread. Maybe, maybe not... she may start to suspect me of being crazy. Holy Schiit Batman! |
I received the chinese balanced power transformer, thanks again for your comparison Ozzy (check's in the mail). I used the power cord from my arcam preamp to hook it up to the wall (it came without a cord). I've plugged in a Mark Levinson 331 (100W/ch @ 8ohm) i intend to sell at some point for a friend, my 55" samsung SUHD tv (~57W), and the RME ADI-2 Pro (~20W?, DAC/digital preamp for computer audio and tv). First thing: the Levinson is noisy. I've been using it for about 6 months, enjoying the power of it but hesitant about what to do in a resale situation. I was not sure if it was due to repairs needed or power issues at the house... Plugged into the C-BPT, listening to youtube music through the tv->RME-ADI-2 Pro->Levinson. The Levinson is now QUIET... TV display appears to show a 'blacker background'. this might only have a few hours of break-in from Ozzy and may benefit from continued break-in, its already great purchase, and confirms how much noise I have coming in probably due to bad wiring in the house/cell towers/smart meters on the house/wifi RF... its a worthwhile purchase. I'll plug the class A 5W guitar amp soon to see if it gets rid of the radio stations being picked up and/or cuts down on background noise. I have a Furutech power strip that I will eventually plug into the C-BPT, then run Levinson/TV/RME-ADI-2 Pro to see if theres an improvement. Eventually I'd like to DIY upgrade the unit based on everyones recommendations, when I get time (next summer). Thanks again for recommending this unit, for less than $200, its an easy purchase in my book. |
I purchased a Hi-End HiFi Audio AC Power Cable Power Cord US Plug - 3.28FT (1M)Sold by: viborg on Amazon for $24.50. The model number on the static bag it came in was: VP2180. Specs listed were: Conductor: OFC Connector: Pure Copper US Out Size Diameter: 16mm Conductor size: 3*4MM2 Length: 1M Made in China There are several models available. I own a couple of these and a couple of the WAudio power cables. I’m pleased with their performance. |
Viborg. Hmmm. https://www.aliexpress.com/w/wholesale-viborg-audio.html |
I remember reading that also. Too many members that are owed products and/or a refund that have not been contacted by Mark or anyone else as of yet. That and many other (dozens) of excuses that are so numerous that the universal odds are against it being possible makes me wonder if Mark is a truthful man of his word? How many times can he tell people that the check is in the mail? I despise liers... |
About 10 days ago I received my 3 power cords, and I must say, they are very good. I believe the company that makes them is called Viborg Audio. Mark and Lynn were quite grateful, for my business and my patience. The correspondence between them and I was great, both professional and friendly. Enjoy ! MrD. |
Well thanks to an Audiogonner I was able to compare the Chinese version to the CPT 300 and CPT 1800. For this review, I will refer to the new balanced supplied unit as the “Chinese” unit when compared to the CPT balanced units. (Which are probably Chinese made transformers). Visual appearance: The first view of this unit is that it is a very well-made, heavy, black, aluminum unit that looks very attractive in my audiophile opinion. The front of the unit has a nice power on button that turns blue when on. And on the back, there is an IEC inlet and 2 double outlets both made by an unfamiliar Chinese brand. Internally, there is a resettable fuse/ circuit breaker along with some substantial wire with a nicely laid out design. Albeit the outlets are daisy chained together (as are the CPT units). First listen, with the Chinese unit replacing the CPT 300. Note: This unit will be powering my low power, mostly digital components that are on a separate dedicated line. I was surprised at how close the Chinese unit sounded to the CPT 300. But there was a slight harshness that could be contributed to burn in. Replacing the CPT 1800 (which is also on its own dedicated line) with the Chinese unit: Now, my CPT 1800 has had Furutech outlets and inlet and higher-grade wiring installed. So, it is not a far comparison to a stock CPT 1800 unit. I used the Chinese unit with a preamp and a couple of tube mono blocks plugged into it. With this configuration, the music sounded harsh but also sounded like it was straining. I was surprised that it powered the amps at all. Too much current draw for this unit. My conclusion is based on a very short play time with the Chinese unit which had ZERO hours on it compared to a well broken in CPT units. I believe with more burn in time it should get better and compete nicely with the CPT 300. However, it doesn’t have enough transformer power to power adequately higher draw amplifiers. So, keep the power draw low 200- 500 watts. ozzy |
Posted 2 pictures on my ozzy system page. The picture of the outside of the unit was taken before I replaced the inlet to a Furutech NCF. No breaker, switch, or fuse is used. Wiring is 12 gauge Military spec silver/copper and the Wago connectors. Not in the picture frame is one more set of black wires that go to another Wago connector along with the orange wire with black tape on it. The tape is for color coding. ozzy |
@t_Ramey @grannyring I am going to have to reset up my system, when I get a new stand next week, I was wondering on the CPT 1200 which receptacle is the first.... that is connected directly to the transformer. When looking at the rear of the 1200 is it first on the left (as I do not remember it being marked)? I only have two audio components, integrated amp and EVS modded Oppo 205, plugged into to the 1200 so I hope to hear a difference if they are both plugged into the first receptacle. |
Ok thanks. I’m going to order some of the Duelund 12g with polycast jacket to try this and replace the Furutech that’s in there now, Alpha 12 I believe. Not even thinking about where my components were plugged in at the 1800 in regards to the first receptacle that gets the transformer connected to it I had my amp and dac on the opposite end. I switched them to the first receptacle and have noticed a nice improvement so it makes me want to see what happens when every receptacle has the same juice. |
I am also using DH Labs spades to connect at all the outlet screws. I then Epoxy over the tightened spade screw connection assuring it never wiggle loose. The small spades used on vintage gear. The BSP model.... https://silversonic.com/products/connectors/spade-connectors/ |
Yes as well as ground. The 8 connector Wago will work. No need for a terminal block with these. The blocks were another option. One 8 gang Wago for hot, another one for neutral and another one for ground. I am also placing a .47uf Audience Auricap XO cap across each individual outlet half for additional filtering. |
Well I only have a 150 and 300. I soldered and used the O spade with brass screw and nut method. I am upgrading my BPT Balanced conditioner which is much like the CPT. I am using these more reasonably priced outlets. I use them a lot and like them. https://www.audiogon.com/listings/lis980b8-porter-port-porter-port-outlets-cryo-various-colors-ac-di... I am also adding a DC blocking circuit as shared in an earlier post. You will need to use two 33,000 uf caps to populate the board for those of you with a CPT1200 or 1800. I will use the new Duelund 600v 12 gauge Polycast wire to do all the internal homerun wiring. I am also going to ditch the IEC and hard wire a nice Duelund power cord to the unit. I am still deciding wether I use my O spade with brass screw and nut system for connectors or the Wago products. Not sure just yet. I am also going to ground ground all outlets and the unit to a Grounding box. Fun project! |
Hi Ozzy. You meant to type Wago. They make the 221 line which actually does a good job clamping tightly onto the wire leads. They make ones that hold 2,3, and 5 separate wire runs. Here they are... https://www.amazon.com/Wago-221-415-LEVER-NUTS-Conductor-Connectors/dp/B0107SYYGU/ref=sr_1_1_sspa?s=... Mark used them in his CPT products. This one is also interesting and can connect up to 8 wires. These could be used to run all the hot leads (two per outlet) to the output of the tranny. You could homerun wire three outlets. Same is done for neutral and ground. https://www.amazon.com/gp/product/B07CN6WR26/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 You will need some sort of terminal block or the above products for such a project. Terminal blocks are readily available everywhere! Well, unless you decide to direct solder each homerun lead to the output. Can be done with some good soldering and a plan. One could even terminate each run with a round spade and use a brass screw and nut to tightly clamp down all the O spades. Be sure to use a nice double wall adhesive lined heat shrink to cover up these bundle so tney don’t touch the chassis or anything else. |
Has anybody used a push in wire connector to connect all the hot leads from the receptacles to the transformer, and one for the neutral for their 1800/1200? https://www.homedepot.com/p/Contractor-s-Choice-Black-8-Port-Push-In-Wire-Connector-40-Pack-67255-0/... |

You can purchase DC blocking circuits here..... https://www.atlhifi.com I purchased the board only and populated it with high quality parts. My buzzing CPT trannys are stone quiet now. Also no DC is getting into my rig. |
FYI; I purchased my Equ=Tech 2Q back in July of 2001. I corresponded with one of the employees at Equ=Tech on several occasions. My suggestion back in 2001 was to replace the outlets with higher quality, cryogenically treated outlet which I did to my unit and it definitely improved the musics sound to my ears. I also removed the duplex outlet with the built-in circuit breaker button and replaced it with a high quality cryogenically treated outlet. |
