Thanks @avanti1960 - good to know. And you hear a clear sonic difference by swapping the rectifier? I’ll try to hunt one down is that’s the case. Is chasing the rectifier more impactful than changing the preamp tubes? When I got the preamp I also got 24!! Stock 6sn7 (3 x matches sets), so I’m overloaded….
Cary Audio SLP-05 First Impression
Hi, I just received my Cary Audio SLP-5 tube preamp this weekend. It’s only been less than 48 hours and I can’t wait to share my experience with my fellow A’goners. If I have to summarize my initial impression of this unit in one word, it would be: WOW!!!
I don’t consider myself a true audiophile, so I don’t really have a strong audiophile vocabulary to describe the sound quality, but a few clichés come to mind:
- sounds like the musicians are right there in my room
- holographic 3D sound
- dead quiet
- sweet & non-fatiguing top end
- deep bass
Couple of things I hope will continue to improve is a tiny bit more punchiness in the mid bass, and smoothing out some occasional graininess at the top end.
My strongest impression so far is the overall imaging of the sound, and the sense that I’m listening to live music. Last night I had my system casually playing in the background when I was doing stuff around my apartment, and Eva Cassidy’s Live at Blues Alley album came on. I was suddenly drawn to the music, and for the first time ever, I finally understand what the description ’sounds like the musicians are right there in my room’ means. It was surreal. It brought a big smile to my face. It was simply beautiful. Need I say more?
This is the first line level tube preamp I’ve ever owned. I do own the Herron VTPH-2A tube phono preamp. Now I know what all that fuss and craze of tube pre/power amps are about. I guess you simply have to experience it to appreciate it. I still feel my Parasound JC2 and JC5 combo sounds great, and I am not planning to get rid of them anytime soon. It’s just that the Cary SLP-05 completely opens up a new music dimension that I’ve never experienced before, and so far it’s been very pleasant.
I will consider doing the ‘Ultimate Upgrade’ offered by Cary at $1600 at some point. Please feel free to share your experience If you are a SLP-05 owner and have done this upgrade.
I have purchased so many components in the last couple of years based on suggestions and comments that I received, and stuff I read in this forum. So thanks to those who continue to contribute and share their experiences to fellow members.
Finally, a big shout-out to @ghdprentice for your suggestion of tube preamps and brought up the Cary brand name in one of my other discussions. This preamp is certainly a keeper.
PS: there are a couple of changes Cary had made to the latest production of SLP-05. It now comes with a universal remote control. The same one that they sell for $190 on their website, instead of a basic 3 buttons remote that I read from some older reviews. Also they no longer recommend stacking the control unit on top of the power unit, and therefore those indentations on the top of the power unit are gone. It is simply a flat surface now. Actually to my surprise, the power unit runs much hotter than the control unit. I always thought the control unit would run hotter because that is where the vacuum tubes sit.
PPS: My unit was shipped with the blue power LED missing. After contacting Cary Audio support, they told me it was most likely dislodged due to rough handling by Fedex. So the unit is now going back and i would have to wait for a replacement. That sucks, but kudos to the customer support folks at both Cary Audio and Music Direct for their great service!
Thanks for reading.

anytime, in pretty much any piece of serious hifi gear... if you see a modern russian or chinese 5ar4 rectifier, the best and most important upgrade is to change to an old stock uk/dutch/japanese or usa made one... in a hobby where the specifics and situation usually dictates the right answer, here is one aspect that is correct and smart to do 100% of the time... |
Thanks @jjss49 - great suggestion and perspective. |
definitely a noticeable sonic difference with different rectifiers. Stock Sovtek- kind of bland overall, nothing offensive but nothing great New production Gold Lion- improved dynamics but thick and veiled sound. NOS Amperex- Punchy bass and very good dynamics but a bit noisy on the top end. NOS Mullard GZ34 F32- Clear, refined, smooth and excellent dynamics and improved sound stage. |
one important point touched upon earlier, which bears some emphasis, is that when a small signal tube goes bad there may be unwanted microphonics, subtly distorted music, rolled off treble, dull sound heard... but when a tube rectifier in a power supply circuit goes bad, gear can (and often does) go up in smoke, and a repair is then needed... hear a loud pop and smelling electrical smoke come out of one’s expensive linestage is not for the faint of heart 🤣 therefore, sonics aside, to me, this is why getting a ’forever’ rectifier like a true blue old stock british/dutch/japanese 5ar4 is a must i remember few years back, a stupid $20 sovtek 5ar4 was the most expensive rectifier i ever used, as after it failed, i had to send my modwright power supply back to dan for a $320 repair |
