if you are interested in 'hifi fidelity' turn tables...

all technics and audio technica are JUNK, the platters in aluminum .. very resonant with a CHEAP plastic cover....

Belt turn table is a must AND if you are almost sensitive to pitch which will change with every single warp in the record, a SPEED regulator is a MUST!@!!!!!!!!!

So , best tt is a must, with a speed regulator, anything under is a HUGE compromise in sound, Debut carbon is junk....(i hear it many times)

once you hear the RPM 9 from Pro-ject with ref cartridges, everything else is a big compromise....

there are other good turntables, like the Stogi REF arm it is very $$$ but worth it, nothing compares to it,

maybe on the 'cheap' side you can consider the AT-LP7 , never heard it yet, I have to visit my hifi dealer soon but I am happy with my current setup which is way higher end.

I tend to agree that having some form of speed adjustment on a turntable is a big plus.
However, the rest of your post is hugely biased and incredibly incorrect, the type of post that I've seen many times online from people, and I'm glad that I'm educated enough both as an honest audiophile, as well as being a long time (45+ years) sales/servicer of audio - that I know better than listen to such garbage talk.

I have just gone through the exercise of re-working a Denon 30L. The results are good. I looked up the Aiwa AP-2400. I notice that the arm is based on the ADC head shell arrangement. On the Denon I replaced the arm with such an arrangement. There are many improvements that can be made. However you have to be prepared to disassemble everything and examine closely.

For example, the head shell connection is sloppy. This needs to be an interference fit. So for the Denon, I used adhesive copper tape which is normally used for EMI seals to add to the head shell joint. That took care of the slop. The arm needed internal damping, therefore foam was put in the arm tube so it was under compression. The arm base was damped with foam under compression also. Dynamat was used to deaden areas of the plinth. There are things that you can do, that no manufacturer of a budget TT can do because of cost. The Denon is now a different TT because I put in the time and effort.

wiseoldtech,
spot on replies. There was a forum in the UK (it still exists) that had an industry professional contributing about 14 years ago. This forum also had some rabid Garrrard fanatics who wanted to attack this man but felt intimidated by his vast professional expertise when he advocated d/d decks.

He presented a list of some of the best of the Japanese 'superdecks'. One of these was the Kenwood KD 990. I saw one on ebay.de and bought it quite cheaply then. It was badly packed, unusual from a German seller and it was dropped in transit.

Unbelievably the only damage was to a corner of the plinth, it played perfectly. I negotiated a refund that made the price @120. I later bought another one for 350.

I should have replaced all the electrolytics but didn't and both the power caps leaked on the first deck.

I've just purchased 2 x sets of caps of Panasonic FR and the cost is around 6 per deck.

It's bearing system is superb and will with bi-annual Slick 50 oil change last indefinitely. As you say the best of the d/d decks are silent compared to idler/belt drives.

Perhaps it is this silence that 'disturbs' those who don't like them - oh yes and rotational accuracy. I also think they look timeless, the KD series has a wonderful Zen like appearance.

It also comes with an excellent gimbal arm with sealed for life bearings but also you can fit 3 other arms to the spider legs.

I would urge the OP to either optimise his existing deck or look to buy a better Japanese superdeck that can be renovated simply and economically.. The most expensive t/ts today cannot compete with the quality of engineering or design - what t/t being made today has the simple brilliant ideas of - end of side arm lift and motor turn off like the KD series without in any way compromising performance.

It's not just ALPUY's turntable which has a return function! Tourtable Aiwa AP2400 direct drive, year 1982 or Rega RP1 or Pro Ject Debut Carbon

Kinda, it has some sort of speed regulator for DD, which you would lack in those you contemplate.

The platter looks better constructed (thicker, more stable, less resonant and thicker rubber mat) in your Aiwa than the newer ones.

I had an old Dual direct drive which had a nice aluminum platter with a nice mat. I saw the new 'hifi' audio technica 2 days ago and the platter is not nice...

The only thing positive about the rega/project is the attention to newer arms which are engineered with a better sounding technology (this is unproved lol)
