Denon DP80 & DP75 Owner's Thread

Hi everyone, I've been thinking of getting a DP 75.One question I have is about the 401 and the 402 tonearms. How good are they? I know the 401 is an ultra lightwieght arm, but thats about it. Finding info on these is difficult

The 401 is an excellent arm, in fact it would take a considerable investment to better it, and if it has all the original parts it came with then the effective mass can be manipulated by several grams. In the original package there are 2 headshell weights and an additional counterweight.

Not familiar with the 402 so I’ll leave that to someone else…

The 401 does not have the common "SME" style removable headshell, it was important for me so I didn't consider it. There is indeed not much information on these arms, from what I understand the 402 is considered Denon's top arm excluding the servo arm on the flagship DP-100 table so when I found a mint 402 in a sensible price I got it, it came with the S arm wand. There's also a straight arm wand available.

Can't say which arm is "better" since I haven't tested them A-B, I'm guessing both are good with different characteristics. I trust Denon's craftmanship of that era so much that I got a second arm, the DA-50. Both arms will be installed on the DK-2300 plinth with the DP-80.
 
The 401 headshell is proprietary, however it also originally also came with 2 headshells, it’s interesting that not many for sale come with 2….

Hi all thanks for the info. I too am leaning towards the DA 402 due to the non removable headshell Plus the odds of getting a second headshell and weights with the DA 401. About other info , both have on the fly VTA. The 401 has a effective mass of 7.5 g. Don't know what the E M of the 402 but it is higher. I also think either arm is probably very good just in their own way. Don't think Denon at their peak would put a cheap arm on this table. I don't know why there is so little info on these TTs. Thanks again.

Just a small point of correction, the 401 does have a removable headshell, it’s just not an SME style….in original form it came with 2 headshells and 2 sets of weights (headshell & counterweight) to manipulate effective mass. Would imagine that one can bring it up to something like 12-15 grams effective mass based on my experience using one.

Generally speaking the 401 is fairly well known as Denon’s top of the line lightweight tonearm :thumbsup:

Very nice. :thumbsup:
Just noticed you are using an Achromat. Is that the 5mm model? What do you think? I'm looking for a new mat and that one is at the top of my list.
I think it is only 3mm? I've forgotten! I use it on top of the stock mat. On its own it wasn't wonderful as it seems to be too light to load the suspended platter properly, but added to stock it did a nice job of cleaning up the sound, especially in the midrange.
 
I already have a question regarding the tonearm, the DA-308. In short i’m looking for a repair manual for the tonearm, or inputs that can point me in the right direction.
The issue i’m dealing with is adjusting the needle pressure. I can set it to 2 grams, measured with a digital gauge. When playing a song and then measuring the pressure, it is now at 2,4 grams. Then i adjust it again and the same thing happens. I know it’s an old arm, and it might be old stiff grease that is to blame, but i’m not sure how to dissasemble the arm correctly. The arm seems to be moving freely and it is not the arm lifter that’s obstructing.
Did you read all the way thru this thread? There are a few posts by someone who rebuilt his DA-308 arm. You can read those and PM with questions. Also, have you tried putting fresh batteries in your digital VTF gauge? Mine tells me it wants new batteries by giving inconsistent readings. You might talk to Steve at VAS. He does tonearm repairs.

I've recently added Herbie's Grungebuster washers under the armboard in my DK-100 plinth. Cost about $9, shipped. Was always 'uncomfortable' with the nylon washers I was using. I hesitate to say it 'sounds better', but the DP-80/DK-100/Stax system sure sounds good to me.

Also, my strobe bulb was getting 'wanky' in that it occasionally missed a beat. Replaced with an LED and is now stable and a bit brighter.

Plenty of other arms out there…I would vote against sticking with just one brand….I went with a jelco 750e…

In the day you could count on 1 hand and have fingers left over the number of actual tonearm manufactures.

Turntables are in almost the same boat at least when considering mid and higher models, Denon did make cartridges though. ;)
 
Hi all. Guess I just joined the club. Woke up this morning to find my DP 75 has a tracking number. Unisound told me 10 to 14 days because of holidays. DHL says dec 27 only 6 days. Pretty fast. My problem is I ordered a protractor for the DA 402 tonearm but it won't be here till jan 5 thru 15th. Is there any way to set this up. I was hoping for a measurement like Technics from the gasket of the headshell to the stylus tip. Or any other suggestions? The transformer will be here before. Also is there any place to get an owners manual?
.Thanks in advance and enjoy your HOLIDAYS
 
Just an observation from reading the Denon tech info re the DP-75/80 sprung platter, Denon stressed their rubber mat as a key part of the platter design. I don't see any benefit to replacing the Denon factory mat.
 
Does anyone here know whether or not the DP-80 fits in the DP-2550 plinth? I recently finished restoring one and I figured if it fits, a DP-80 or 75 motor unit would be an upgrade from the DP-2000 I have now.

I have looked around for a while now but have been unable to get a conclusive answer. I'd hate to buy a DP-80 one day and find out it won't fit.

Here's my TT:

You could download the free DP80 template on vinyl engine and take some measurements.
I found the template. Unfortunately there's no template for the DP-2000 that I can find. Does anyone have one by any chance?

From looking at the DP-80 one and my raw plinth it looks like it should fit. The DP-80 template has a smaller extra cutout in the back compared to the DP-2550 plinth but it doesn't look like that would matter?

I have joined the DP-75 club.
I am in the process of restoring it now. See my thread elsewhere in the Turntable section.
The tonearm (DA-401) is being modified due to broken unobtainium parts. The headshell socket.

Looking forward to when I have this beauty done.

I would print it to scale and put it on top of the base you have.
