Dab out of synch

In my dining room I have a Denon M38dab mini system. In the kitchen there was an older FM only Denon, which has broken.
I was a bit pleased as I could only have both on fm because if I used DAB on the one there was a bad echoing delay.
I have just replaced it with a Denon M39Dab mini system.
If I play both on DAB on radio 2 there is also a slight delay causing an odd echo which I cannot bear.
How can this happen and what can I do?

Can that make a difference?
There should be no delay at all on FM but if one were still on DAB then you will notice quite a considerable delay between FM and DAB.
Both say FM 98.3. On then front
About 1/4 sec echo delay and cannot bear it!
I can't explain this, unless your ears are much closer to the speaker of one radio than to that of the other.
I agree.
Aha. That makes sense.
I've found my Pure Evoke Flow suffers from poor FM reception when plugged in, but disconnecting the plug and using battery power greatly improves the signal.
The radios are about 15 ft apart.
The sound is like an echo, especially speech. You can easily hear individual words starting in one room then in the kitchen.
If a say BBBBBBB as fast as possible that's the speed of the delay.
Just did a side-by-side comparison using a good quality FM tranny (Morphy Richards 27006) and I'd say that the One Flow's software demodulation delay is equivalent to a good sized conference room, i.e. about 50-75ms. It isn't really noticeable and you have to listen to recognize it (in fact I'd never noticed before). My sympathies to Cjwontv as I'd be driven doolally by a 250ms delay too.
Would this be grounds for returning it?
Just out of idle curiosity why have you got two radios on in two separate rooms all the time?
Still it's 45 mins and would like 2 radios to play at the same time. Not unreasonable.

Boy spellchecker can be annoying sometimes!
A sensible idea. My solution is to use 10 metres of screened multi-core cable. It starts out in the sitting room, goes through the middle room, and into the kitchen. In the sitting room, it can connect to a line-out on the radio, or to the computer sound card. In the kitchen, it connects to some powered speakers. When moving from 1 room to the other, I only have to switch the speakers on in the kitchen.
It is best to solder stereo jack plugs onto each end of the cable.
If buying stereo powered speakers, go for either two including bass units, or the ones known as 2.1 , which are a bass unit with 2 slim stick-like high-frequency units. Avoid the cheapest ones, which are the two sticks by themselves, as they have no bass and are no good for music.
So have 1 radio, and pipe the audio through from room to room...
Agreed.
