That is a tough call. 25K? Hmmmm. Ok. here we go. What I have done is take WhatHiFi and AV Max issues from Jan 2008 and listed their reviews of HT packages I have seen around that price. The comments are purely those of WhatHiFi / AV Max.
1. LG HT 902TB
Price 24,900
FOR: Good Pictures, even better sound, build and looks
AGAINST: Not much given the price.
VERDICT: A stellar system for very little money,
2. Samsung HT-X30
Price: 13,900
FOR: Great build and design. decent performance. Wireless upgrade options
AGAINST: Lacks the power, scale, and pitch of the best in class
VERDICT: A worthwhile small room system, but you can get more living room ooomph from the LG
3. Panasonic SC-PT850
Price: Unknown
FOR: Good Specs
AGAINST: Disappointing picture, rivals offer more sonic detail and punch
VERDICT: An OK system but rivals have a serious edge
4. Sony DAV-DZ750K
Price: 26,990
FOR: Build and design. Good performance.
AGAINST: Slightly forward treble. Picture beaten by the LG
VERDICT: A good system but not best in class.
5. Samsung HT-TX25
Price: 19,900
FOR: Flexibility. Convincing sound and picture
AGAINST: No HDMI, and not much else
VERDICT: A very decent all rounder, but not class leader.
6. Sony DZ855KW
Price. 39,990
FOR: Good picture, stylish speakers, wireless flexibility
AGAINST: Fussy infrared signals to rear. Premium price. Poor Auto configuration.
VERDICT: A system that offers good picture and sound but has flawed wireless convenience.
7. LG HT762TZ
Price: 29,990
FOR: Smart styled and with good specs. Can upscale to 1080p. Good integration. Fast sats.
AGAINST: Some noise to picture. Treble sounds a little detached.
VERDICT: LG's design art range is shaping up nicely indeed. This is a solid cinema system for under 30,000.
8. Onkyo. HT-SR800 (B)
Price: 45,000
This is AV Max award winner for 2007-2008. AV Max has this to say.
The SR 800 is much more promising than the S990 even though it is not offering anything new in terms of features. It sounds a lot more refined and authoritative for approximately the same moderate price; which is why it comes highly recommended. It may not be the best thing you have laid eyes on, but it does its job dutifully.
9. The Philips HTS-6600 and MCD-288 have won the silver and bronze awards, but I do not have any details.
If others can pitch in with more details of these or other models, it will be appreciated.
