I love the SP1 bi-wire cables and MA1 interconnects to put it mildly. Sorry I did not tell you sooner.

I received them the last week in December and I would estimate I have about 400 hours on them. I couldn't be more pleased with them. My system is fairly modest...FLAC files ->Schiit Modi2 Uber -> MA1 interconnects -> Rogue Sphinx integrated amp -> SP1 cables -> qAcoustics 3500 speakers. The frequency extremes and the overall soundstage improved dramatically over the bi-wire Blue Jeans cable that I previously used. BTW, they were great out of the box.

Mr. Morrow,

After many years of using DIY cables I decided to try something new and different. I am very picky and focused on what I buy and tend to do a ton of research before I make a choice and then do even more research to ensure I am pleased with what I buy, I only buy American made products and always support small businesses.

I am NASA certified in PCB (printed circuit board) repair and master certified in soldering and felt my home made cables were far superior to what you can find in big box stores. Enter Morrow Audio, upon unboxing the cables I could see that these were expertly made and the technician signed sleeve set it over the top.

I purchased the SP1 and the hookup was easy and provided for a more secure fit than my DIY cables. I immediately fired up Diana Krall's greatest hits and was completely astonished at how different it had become. The bass pounded and was not muddy and rolled off with ease, the mid range felt more warm and enveloping, the highs are now brighter with no harshness to accompany the music. Next I fired up Pink Floyd's "Wish You Were Here" and guitar riffs immediately came to life, I could actually hear the pick strum the string which I have never heard before. The sound stage actually came to life and I felt as if I was right there with the band.

Our family is big on movies as well and these cables fell nothing short of being exceptional. Bass was more tight and controlled and voice dialogue became more focused and transparent. The movie sound tracks have also come alive and my children now enjoy the older movies which have become new again.

Over all I am very pleased and now recommend these cables to all of my friends. I have not noticed anything different as far as break time goes but I think that is because I have less than 100hours logged with these cables. Thank you for an outstanding product and my only regret was not buying the next higher cable, the SP2.

Recently we had our living room redecorated, unfortunately we had quite a long last minute unexpected delay as the decorator had to reschedule some work.This meant that unfortunately our Hi Fi system was boxed up for much longer than we had planned, we've missed it! It is back in action now and we are delighted with the improvement that the new SP1 speaker cables have created !!! We are experiencing all the benefits that other people have reported in your reviews, amazing and excellent.

"Mike's SP1 although entry level, never sound the slightest bit entry level. What they did for my system was increase the level of effortless performance, open up the sound stage in all directions. Microdynamics is amazing. These are amazing cables and Mike Morrow provides a first rate service behind his cables with excellent communications. Many thanks for provide such as a great product and service without charging five times the price for it. Absolutely recommended! Mun-Wai

I've probably put 60-70 hrs on the SP1's. I'm not worried about break-in anomalies. The cables sound fine, and I learned from the Morrow SP2 biwires I was using with my previous speakers just how nice your cables are. Yes, greater detail, yet a full sound, quite relaxed, and greater extension than with my DH Lab cables. I'm using the Morrows with an Almarro 318B and Almarro M33A speakers that are crossoverless with two full-range drivers. Your cables fit in just right.

"I don''t know what kind of ju-ju you''re playing with, but that''s some good ju-ju. The cables are still settling in (after your burn-in service), but there''s already a noticeable lifting of the sound, as if filtered and purified. Great detail and great warmth, all at the same time. Honestly didn''t believe that cables could make such a fantastic impact... until now." Justin R

"I had Solstice 6 and then ordered Morrow Audio SP1 for all 5 channels. HUGE upgrade. It was so much clearer and more engaging. Much better separation of instruments and voices in movies. They also have a 60 day return policy. Also, the SP1 is so thin it was easily routed to the rear speakers." Audiogon, Joeyboynj

I've been very pleased with the cables. So far, I've tried a pair of the MA1 interconnects and a single run of SP1 for my center channel speaker. Out-of-the-box sound quality was impressive -- I used your burn-in service for the speaker cable but not for the interconnects. I've mainly noticed that the cables deliver a big, detailed soundstage, and deeper bass than what I had been hearing. Considering their construction and performance, I think your cables are an outstanding value!

Sincerely, Steve Kindig

Thanks for the follow up. I have been busy breaking in your cable. I think it comes to a stable situation now. And then I become busy again... enjoying all the good music that brings out from your cable. So far, i feel all the goodies other users says about your cable. One particular song by Eason Chan (a Hong Kong singer) i listen recently, I can feel the movement of his head while he is singing. I have never experience such good music at home before. Now I am re- listen to my collections, knowing that I am going to hear those details that wasn't there before. Will have more feedback later. Francis, Hong Kong

Hello, My name is Matt Miller and I wanted to drop Mike a line and say how much I am loving his cables. In fact my whole family uses them, we are hifi nuts. I have 3 brothers and a 75 year old father and we all use Morrow Audio cables. My brother Dave finally got rid of his MIT Shotgun S1 cables (my recommendation) and purchased a whole balanced set from Morrow Audio. His jaw dropped when he first listened to them, it was like taking ear muffs off! Since then they have just gotten better. I really appreciate the way in which your cables can be purchased, which is affordable for every one! Thank you Mike, Matt Miller

"Right out of the box the SP1 cables spanked my Audioquest 8tc, which were highly hailed by Stereophile as cable of the year! Somehow Mike has managed to put an audio genie into these cables to grant all your audio wishes!

These cables do everything right! Depth, detail, soundstage, bass, space, air, rythm, pace. The soundstage extends way beyond the speakers! They have not even burned in yet and they have exceeded all of my expectations!

I have had well over 50 different speaker cables over the years, some in the $3000 price range, and they have not come close to the SP1 cables. It is a real kick in the ''audio groin'' to have paid an extravagant amount of money for cables and then have a pair costing such a minimal amount out-perform yours hands down!

You owe it to yourself to give these a try before you purchase anything else! Refunded in 60 days if you don't like them, you can't go wrong!

Violins float in the air with incredible detail, same with gituars. Symbals splash, voices hover in front of you, and the bass is tight and clean. I have heard little detailed things in the music that was missed. I can't say enough good things about the SP1 cables. I am going to try the SP3 in the near future just to see the difference. I can't imagine how they could sound better! Thank you Mike for breathing life into my system." Alex, Spanaway, WA

Solid Core: Using solid core wire removes the stranding distortion found in stranded wire designs. This eliminates the smearing effect, allowing much more information to pass through.

Small Gauge: Using a proprietary small gauge wire removes the skin effect distortions that are unavoidable in larger gauge construction. You will hear things in your music that you never heard before.

Individually Insulated: Insulating each strand of wire individually allows the signal to flow unhindered instead of jumping from strand to strand. Great detail in your music is achieved. The emotion of the music comes through.
