  1. As an example if ones hearing test audigram looked like this (first picture), one has significant loss and if the left and right ear were more uneven, then likely to have issues with appreciating stereo imaging, very rolled off highs and the hifi system sound balance you might prefer is a very bright sounding one. Average males around 60 with normal age related hearing loss would be up to 12-14khz limit at normal levels and overall the audigram loss of about 10-20dB, which is not significant enough to impair music enjoyment and the volume can be adjusted upward to compensate. Second picture of average loss by age and gender.
  2. here’s a list of potentials http://www.audiophile.no/en/articles-tests-reviews/item/426-amplifiers-with-processor-input
  3. It’s a fair question and has been discussed many times in other ways. At 60 for average males and better for females hearing ability is still good enough, with high frequency loss at about 12000-14000 hz, and most recorded music reaches about under that. At around 75-80+ it starts to reduce greatly but can still be enjoyed on average even with no more than 10000hz ability. One in five of the general population have hearing loss problems depending occupation, disease and health, male or female. Heaps of online info out there, free online and private free hearing centre hearing tests available. Reason why older people spend big is they have accumulated wealth and years of experience to know what to buy. Some graphs below
  4. If the below picture is the actual one, the rear port outlet edges to the rear cabinet do appear to be rounded enough to reduce chuffing but it may still be audible from listening position, if not don’t worry about it. If it is audible from listening position it’s terribly poor design as it’s so easy to avoid this. The port noise could be happening inside at the opposite end of the cabinet where the port pipe end does not have a similar rounded flare or 90 degree edge to stop high velocity air rushing past the pipe edge. If so, you could try sticking several layers of hardware shop window foam with sticky back or general foam with rubber band or tape. Experiment going forward on this and try replicate the flared end or 90 degree pipe edge at the rear but don’t install the foam inside the port, only at the pipe edge outside it.
  5. IMO the Vincent’s are well built but generally bland sounding so MF, Roksan, Yamaha AS 1100 or 2100 and similar would be better. Another way that has much more potential is to look at the post on the giant killing Stereo Coffee preamp for $500 built or $250 kit, add a $700-1500 used true audiophile class power amp and DAC or the CA streamer and similar. The preamp and power amp will be as good as nearly a $6-10k rrp integrated. This would be a good amp platform for future upgraded speakers.
  6. Below is a picture of the Onkyo amp inside and if means anything at all it looks like they have tried to make this better at the price with dual mono design transformers resulting in a 17kg weight over others at this price that may be less. Searching for general independent user reviews the model does not come up very well so either that means it was not that good and famous or that the market failed to realise for other reasons. Compared to something like a Roksan Kandy integrated amp that has a lot of good reviews that I have personally used and confirm it is above average at the price. There is generalised comments that Japanese designee midfi range amps sound good but not as musical or detailed as European market amps so that may give a rough indication of what you get by trying different amps. One way with less risk and loss of money is to buy a good condition used amp for about less than half new price and if you don’t like it sell with little or no loss of money. For Aud$1400 new price of the Onkyo 9555 you could find $3000-4000 new retail price amps with better potential. In my experience after trying many midfi amps there is about a 5-30% subjective difference in trying different amps that match your speakers better.
  7. My apologies for mistaking your amp as an HT amp. So then the general question is how good are $Aud 1400 integrated amps. Generally at this price range it is considered lower midfi quality and a $3000 amp should be better from other manufacturers like Musical Fidelity, more expensive Yamaha like AS1100 or 2100, Roksan and others. Search for regular posts by Cafad on this forum reviewing many integrated amps to get an idea of what is available.
  8. It depends what best sound you are looking for whether two channel stereo for mostly music quality or home theatre to watch mostly movies, media and similar. You can see in many past discussions here and other hifi forums that for your item value of about AuD $1400 home theatre amplifier two channel stereo music is not usually very good. It is common for such units to not sound clear with enough details. The Focal speakers need a better quality two channel amplifier. The problem is that the HT unit has too many functions which cost money to build and the amplifier power section circuits and design (power transformer, capacitors and other items) are lower cost and quality than a dedicated two channel amp with less functions but more construction cost and quality devoted to the same amplifier parts resulting in better power supply and sound quality. You can either change your HT unit for a better sounding two channel stereo amp or get another HT unit that has a bypass function to switch to a 2 channel amp in the same system so you have both.
  9. Depends how you are using them. The app on the Bluesound is better and includes excellent functions but if you are streaming at distance the range isn’t that good and drops out often. Also, the USB on it is designed to match with a USB stick and you may need to reformat things to get it to work. For example, it won’t read files from a simple USB drive. I would google Bluesound Node problems and see what the reports are. If your using direct Ethernet or modem is close it should be more reliable. I found my old CA NP30 setup and connection way easier, sounded way better, never drops out, reliable and reads USB drives with no problems. Based on my CA experience I would be going for another CA streamer.
  10. You should try out the Bluesound amp first to see if it works well on the speakers. There are lots Other amp options with or without the intergrated streamer option or simply add on a streamer from the main manufacturers so check all their products from NAD, Yamaha, Rotel, Cambridge Audio, Audiolab, Musical Fidelity etc. You are likely to get a better integrated amp sound from a non combined streamer and amp unit such as the Yamaha As701 amp and others.
  11. There is a lot of good expert discussion here https://www.diyaudio.com/forums/multi-way/280830-advantages-ring-radiator-vs-conventional-domes-concave-convex.html I really don’t like the Vifa xt25 and it’s variants, it’s mostly a cheap and annoying sound to me despite the good reviews, measurement performance and commonly found everywhere by speaker makers mostly because its cheap at $40-50. Some $50k speakers have even used them. I really like the expensive Scanspeak 7100 type ring radiators, extremly clean, not splashy, highly micro detailed and image amazing.
  12. 7x5m is a good size in terms of avoiding cuboid in the horizontal plane. Assuming you plan to place the speakers on the 5m end, with the sloping ceiling it theoretically might provide an uneven ceiling reflection if you want the flexibility of placing speakers across the 7m wide wall, however it may not be audible in reality. The 5m wall end allows you to have a good 3m equilateral stereo listening triangle with 1m either side of speaker to side walls, which will work for most situations but it may be less perfect for some very wide types of speakers like electrostatic, ribbon or large horn type speakers so retaining an option for that on the 7m wall including an argument for not having the ceiling slope should be considered. There are heaps of online sites and discussions for best acoustic (acoustic performance) stud wall construction to refer to. Also, consider that in an ideal listening room you want be able to use it all day and night while others are sleeping or trying to enjoy there own lives in peace. Therefore in the design, noise reduction breakout (noise nuisance reduction vs listening acoustic performance) to the neighbours and internally, which means higher acoustic grade product panels like single sheet of Souncheck or double layer standard gyprock (double the weight so can studs structurally cope) sealing airgaps and transmission paths like doors, thicker window glass 6-10mm or double glazing if there are any windows and common ventilation ducting treatments (silencing and zone shut off) etc. Modern Building Code energy efficiency performance requirements meaning walls of R3.7 and ceilings of R4 value should take care of the external noise insulation aspects but not the panel material or thickness needed to attenuate noise transmission and not internally between rooms. Expert acoustic consultant advice may help to avoid the guesswork and errors.
  13. Yamaha NS1000 can work with non tube amps quite well, depends what sound balance one likes. Depending on who is selling, how quick one is but they can be found from $800-2000.
  14. Great suggestions, since we are recommending vintage Kef 105, may as well mention the Yamaha NS1000 that come up for similar or a little more money, heck also the Spendor 1/2, S &. SP100, BC3; Proac EBS and Studio, Studio 200 and 250, Response 2, 2.5, 3, 3, 3.8 and B&W 801F and bunch of others if they come up.
