753F's Hitting Endstops on Creed/Metallica & hello?

Posted by: Nime on 01 December 2002

Hi,
Just a polite hello first. As this is my first message to the group. Brace yourselves.
We now have a Marantz CD-63SE, Naim 72/180 and 753F's via 2x8 metres of Cable Talk 3. The LP12, Ittok, DL304 sulks unnused. (Since the Maranz arrived in protest at the lack of new LPs).
While I like to listen to Amsterdam Loeki Stardust (recorder quartet) (and Mike Oldfield) at realistic(?) levels. My lady wife likes to crank it to 12 o'clock on Creed et al. Without ear defenders I can't use my Tandy sound level meter to check what she's doing to herself in actual dBs! (We are rural detached BTW).
The other day I heard a sort of rhythmic popping and suppose it's the endstops on the bass units meeting the cones coming the other way. It was out of rhythm.
She has complained as to a lack of bass since the arrival of the Naim gear compared with the A&R A60!? She's hated every single upgrade since moving on from the original TD160AB, SA606 /TM1 combo in the early 70's(?). We had a 20 year(?) love/ hate relationship with early Kans which was (almost) resolved with 2 large passive DIY subwoofers. (To cater for my classical organ tastes and the odd techno-mania-moment)The A&R used to glow in the dark! The Naim sauntered.
The "listening room" is the first floor of our open plan "cottage" of roughly 100 cu.metres. The 753F's sit on bolted-on Blackfoot (low H-section cast-iron stands) with spikes onto small coins on top of 18" square concrete slabs. On thin-carpetted wooden floors. I've bridged the paired terminals with thick copper wire on the 753F's. (Had no instructions with the speakers)
I have (humbly) suggested a pair of used Dali 850's to Her. For some seriously overblown bass! But I still love the 753F's myself after the endless Kans war. The Kans are sulking beside the Linn on top of a cupboard).
She won't change. Any good ideas please?

Best regards, Nime

What a great first post!

The bass units on my Isobariks can hit the end stops at tolerable levels, but that's with material with low synthesised bass in it (in fact it's only one track that I've experienced this with). I don't think Creed has much real bass.

So I suggest turning it down, putting socks in the ports, or investigating ATC.

The photo on the Mission web site makes the 753 look enormous, perhaps it's not and you simply need larger speakers? It's also likely that a better power amp with more go would help. Perhaps your dealer could loan you a new 250? This would obviously exacerbate the mullet, but sometimes might is right.

Hi Paul,
Thanks for the kind words. Regarding the '250 I have to admit to a lack of that amount of disposable capital. Particuarly as it would involve getting a power supply. This is what brought me to the '72/'180 level in the first place.
Regarding the 'loaner' from a dealer. I have yet to find a Naim dealer over here. Most are near the capital. A £20 bridge crossing (each way) and/or 3+ hours away by motorway.
I have been considering advertising my LP12 (Ittok/Valhalla/Denon DL304) over here as a swap for a HiCap. Or cash to purchase a used example of the same. I doubt the Kans will fetch much these days. Particularly after dismantling them and fitting the units into heavy plastic spheres for a couple of years. (Don't ask! There's no going back to the kiddy's shoe boxes afterwards!) Then the 753's became suddenly affordable. I'm competely out of touch on used values these days. Is an early (updated) LP12/Ittok etc. worth a used HiCap?

Best regards, Nime

That's an easy one. Yes.
