Jade series is very expensive, like impossible for me to get one., but I wish to have it 
Wharfedale DX-1 HCP RM4,800?

I want to ask you guys about the price for Wharfedale DX-1 HCP speaker package.

Last time on Monday 18.05.2015 I went to Desa HT @ Lowyat to buy this speaker.
I was very sure that the price should be around RM2,400 - RM2,800

I was very sure because when I visited the same shop last 3 years, the seller offered me RM2,500 (dua ribu setengah)

Last year (2014) a friend of mine also told me that he find the speaker sold for RM2,500 at Desa HT.

I checked with WhatHifi, just checking,

Denon AVR-1910 Tested at £450 was sold for RM2,800 in Malaysia.
Wharfedale Diamond 9.1 Tested at £150 sold for RM950 in Malaysia.

Wharfedale DX-1 HCP Tested at £400 SHOULD BE sold for RM2,488.88 in Malaysia.

I am very surprised when I actually want to buy this speaker last Monday, Desa HT selling it for RM4,800?!!!

I am very disappointed, but never argue with the seller. But I did tell him that I thought it was RM2,500..

Diamond 9.1 is the best speaker as compared to other speakers I ever owned.
It performs very well with all music, classic, rock, black metal.
(Unlike Mission incapable to drive metal music without harsh)

Diamond 9.1 is good enough to test whether one amp or AVR is good or not.
Years ago I paired this speaker with Denon AVR-1909 & 1905, it really produce lifelike sound quality.

But finishing is the big problem. Speaker cabinet start to tear and broke due to age.
I want to rebuild speaker cabinet myself and maintain the original parts.
Many cash spent already on woodwork, but still don't get to produce a nice one.
Buying new speakers seems not promising same quality as Diamond 9.

I only have 2 options, whether to rebuild speaker cabinet for existing diamond 9.1,
or buy more expensive speakers like B&W 

You are right.  Expensive does not guarantee best sound either..
Also we don't know maybe the expensive part is more on finishing than speaker itself
Honestly to say that i did hear dynaudio speaker in hifi showroom and it did not impress me at all.
although it is an expensive speaker in the market. Maybe not my taste.

If anything, sonic differences between different speaker types is actually one of the easiest thing to hear for. The better advice would be to choose based your own listening taste and preference, regardless of price.
But if the more "expensive" speakers sound more enjoyable or suitable to your own listening taste and the wallet is feeling generous, go for it then.

But whatever it may be, please don't fall into the "sour grapes" trap.  There are some who will hentam the more expensive things saying that it's a con job or whatever, but actually they are just jealous of other people's affordability and have some inferiority complex of their own. Not referring to anyone in the Wharfedale thread here of course (but in some other threads  ).
