In my neck of the wood this CD player is around 100 - 150 bucks in working order. Back in the day this wasnt a cheap one. It has good transport and DAC. its a 16bit chip with eightfold oversampling. However,the sound stems from the analog output stages which is a discretly built FET design called HDAM. Marantz used this also in amplifier linelevel driverstages at that time. Anyway,from today perspective the Opamp used in the filterstage at the DACs output is a weak spot. Its NJM 2114D. Decent at the time but there are way better sounding ones on the market now. Imho this player is a worthwhile upgrading project. You can squeeze even better sound out this rather easy. Just my 2 cents.

I had/have one of these. Had a failure like that and it ended up in storage. It was a really nice sounding unit and this video makes me want to go find and repair it.

Just wanted to wish you the best. Hope you and your family are not affected by the fires.

!Is it enough to run a cable from my amplifier to the vu meter from where the speaker cable is connected?

I picked up a Marantz CD6000 CD recorder in the gold finish from Barnardos for £35. Works perfectly, makes great recordings, but you do need to purchase music only cdr, not data. It didn't have a remote control, but I managed to pick one up off ebay for a good price. I have an Onkyo C7030 that I got ex display from a local hifi dealers. A good deal at the time, so I'm good for CD players for now.

Real nice unit , I had one for a few years, finally gave it to a pal who had always wanted one.

I cannot find Nobsound AV-525 on Aliexpress in 2025. But HTA-200 is still for sale. Dayton survived this amp? Thanks for the helpful comparison!

It has no ground cable for a reason. wall outlet ground connections often generate distortion caused by other equipment in the household.

SUBBED to you. Continue your excellent efforts.

Hi! I just purcased this eq and when I connected it to my powered speakers I noticed any difference when it´s on or off? Eq rca out to speaker rca aux in.Can you help me what is the problem? Do I need a separate amp with it? Thanks!

Wow nice Marantz! I got lucky finding a Pioneer Elite DV-45a dvd/sacd player for $6 at goodwill. It’s Burr-Brown dac chips are very musical, slightly warm but punchy. I guess the requirement to play sacd through its analog stage placed a high demand for good playback.

Great job - I love seeing a broken item get a new life!

Nice machine and review Rick. I have a late 90's Rotel rcd951 player and use it weekly sans external dac and it still sounds amazing according others and myself.

What a find Rick well done.

awesome find! my marantz 5 disc came from a thrift shop for $25 and i've been using it for years now. sounds great through an external dac.

Hey Rick, informative video. I go to a savers right down the street almost every day because they always are putting out new CDs and good ones, i had a bought a few cd players from their, i found a pioneer elite Blu-ray DC 45 a , it' was there flagship back in the day and still goes for $89 on Amazon, it will play blue Ray cds 5.1 , and SACD. It has a lot of connections for surround sound, but I use it as a transport. I bought a couple of SACDs , Fleetwood Mac rumours and the first dire straights, imports SACD from China and they they sound amazing. It's to bad that mp3. killed SACD and blue Raymusic format . We went backwards with music quality when that happened. But anyway I have been lucky and find a lot of good cds and they all seem to be like new. I went there last week it looked like some turned there whole collection over because it was all really good classic rock albums. I had to stop myself at 20 cds. That's the reason why I started collecting CDs again because of savers. They are $1.99 and sound better than streaming off tidal in my opinion. I like how your idea on these videos on saving vintage gear and speakers in this throw away society we live in we need to start saving vintage gear from the landfill.

I have been trying to find a good CD player at thrift stores for YEARS now! They're getting more scarce. I'm currently using a Sony DVD player for CDs. Good to know there's drop in replacement parts for some older player. Real nice Marantz unit.

Before I got my D70pro, I was fortunate to find the last of the Drop version of the Topping A90 Discrete headphone amp, and it is the center of my world right now. i plan on using the A90 as a pre-amp for my speaker system, the sound is so exceptional to my ears. I paired it with the D70 mainly due to the awesome screen. Love the freq. response graph. Anyway, the sound together is incredible. I bought the very reduced-price Edition XS headphones and they're great, too.

I bet those are fake toroidal looking power sources.

So, what amp is a great match for the headphone output of this K11 R2R?

Great review my friend. Happy New Year!

Thanks for the honest review.

Nice review. One of the things you did here that is really helpful is you talked about applications for this amp. Lots of reviewers talk about “soundstage”, “depth”, etc. What I, as a consumer, want to know is what applications play to a component’s strength and which play to its weaknesses. For example, I just finished buying the amps needed for my project and it was not easy. All I really had to go on was RUclips reviews. General descriptions of equipment is nice, but it doesn’t tell me how well it will address my sonic concerns or the likely synergy with my system. In the end, I chose the Galion A75 for the tweeter/midrange because it seemed from the reviews to be the most “tube-like” SS amp and that was what I was looking for. On the woofers, I wanted tons of power and control. My choice was a Buckeye amp build of current generation Purifi Class D amp modules putting out either 425 or 450 watts per channel. Gain matching is not an issue because I’m using an electronic crossover. So in my application, I could care less about the bass performance of the Galion amp; it’s never going to play below 200hz. I only care about the treble and midrange performance. If the reviews had said the amp was stellar in the treble/midrange but weak in the bass, I still would have bought the amp. I encourage you, as you review equipment in the future, to consider and share your thoughts about what situations a piece of equipment would be good for. Is it a question of something like bass performance or whether it might mellow out an overly analytical speaker. These practical considerations all too often get lost in too many reviews. Telling me an amp is great doesn’t tell me much. Telling me why, what it does well, tells me much more. Best of luck.

This would pair well with the new Project Audio Speaker Box 3 E speakers, Topping D50 III DAC and a REL T/Zero sub for a high end desktop setup.

Nice, thank you so much!😊

Now find a pair of JVC SK-404 cabinet speakers and show me what you'd do for them...........

Hola Rick, what would you rather recommend for listening to CDs - SMSL PL100 CD player or DVD player + SMSL SU-1? Both option cost the same where i live. Thanks for any answer.

1 mic? Tilt speakers in , but 2 mics at 1 meter distance will be best.

I'm going to order two! Thanks for letting me hear the rekkr on your video. It's got plenty of present bass. I just ordered a magni, modi, and rekkr stack! Not even 5 minutes ago while watching this! I really hope Jason changes his mind and saves the rekkr! One can hope.

when heaphones are plugged in are the RCA outputs disabled?

What happens if the unit is turned off, does it still route through a particular set of inputs / outputs or does it go open circuit on all channels?

hi, can this be used before a headphone amplifier? or will it produce too much noise? 😊

Thanks for the review. This is a strong contender for the Wiim Ultra amp

I think the far superior user interface/app makes the mini the clear winner. I run the mini streaming direct via Tidal, Spotify or Amazon music to an SU-1 DAC via optical and the sound quality is startlingly good, even with a basic power supply. Still looking for a good quality inexpensive power supply to take this pairing another step higher.

The difference could very well be due to the difference in height, although I'm certain the extra weight also helps improve rotational stability and vibration mitigation. I've experienced adjusting VTA on fixed height tonearms by adjusting the mat thickness and even experimented with using two mats usually with good result with multiple carts, including the VM95E, Nagaoka MP110 and other from the MP series, and AT's 500 series. I would be curious to know how the extra weight could affect the belt and the motor pulley over time. Btw, have you replaced the belt so far on the Cambridge TT, and if so with what brand? I couldn't find any Cambridge branded belts, or headshells for that matter, for this model but I'm assuming some AT belts could do the job, as the plater design and motor layout seems very similar. Any thoughts? Thank you!

Always solder with the iron tip under the connection and feed solder to the top to ensure it flows all the way through the connection. Heat rises.

Just get a Loxjie-a40

Hello 👋 Excellent video. Is that board MDF or Plywood? Super effort and outcome by the way. Please put a detailed video how you paint your enclosures. They are elegant by sure. Really want to learn. From 🇮🇳 india.

Thanks for your review. I have so much to learn and I have watched so many reviews that it all just gets mushed together in my brain. What I liked in your review was its clear usage comparisons and honest approach. Thank you.

Can it operate good with speakers 6ohm 120-140wt per one chanel?

Neat little box. Good review my friend. I hope you guys have a very Merry Christmas & a Happy New Year.

Great review! I love this DAC so much that I had to purchase a 2nd one. Finally found an affordable DAC w/ the warm yet detailed sound that I've been looking for. I prefer NOS mode as well. Merry Christmas!!!!!

Rick, your reviews are getting better and better. This is such cool little amp! Merry Christmas!!!!!

Picked up a SU-1 at Black Friday price ($67). Love the AKM sound feeding WiiM stream into my vintage dorm room system (Kenwood 4070 receiver, Akai cassette deck, large Advents). Now I can listen to sharp, detailed digi tunes and sweet full sounding vinyl (coming from a Fluance 85) on the same system. What’s not to love? This really is the golden age of hifi. Thanks for a great and concise review.

Double click the center of the select knob to back out of menus

I have this Smsl Su-1 + Arylic S10+ combo with Fx Audio T03 tube preamp(modified) which sounds great. But the S10+ drops out intermittently while on wifi and USB pen drive. It gets worse with BT connection. Good thing I don't use BT. The Upstream crashes frequently. If it works, it's too slow. I bought it for $34.20 on sale + discount vouchers.

I bought this unit a few months ago and so far so good. We'll see. I noticed you referenced that ASR found this unit does not affect the sound quality. If you look closely at the ASR review, Amir does not hook it up as a switcher, but merely in parallel with the speaker wires to use it solely as a fun meter.

soft amp vs hardware?...please advice

❤ wow i can hear the difference! Thanks
