change amps or speakers


I am powering Eminent technology LFT8bs with quicksilver M60 monoblocks.  No preamp - I am running a dac directly to the amps, which works because with this configuration I am using very little attenuation.  Problem is it is obvious that the ETs require more current and/or wattage- the detail is there but not the punch and there are times when I am maxed out on volume at 12 0'clock and need more. Question is do I change the amps or speakers - I love the quicksilvers and put some serious $ into modifications.  A well respected friend/tech highly suggested I seek out a used pair of PSB stratus golds. I have a medium sized family room and like detail neutrality but need more rhythm and dynamics. Thanks you.

Most of you confirmed my instinct: replace the speakers with more efficient ones that will work with the quicksilvers. Any recommendations in the 3,000 range new or used?

@majorc Did not realize you had older Mono 60s with EL34s. Great tube, less drive. +1 on earlier KT88 suggestion. Genelex Gold Lyon KT88s, a good tube preamp, and good OCC interconnects could give you more drive and transparency you are looking for.

Or, if you go to different speakers, what color stain are they and how old are the LFT8s? PM me if you plan to sell them. May know of a buyer :)




Thank you for your input. Before I make a decision to purchase the KT88s for use with the ETs, does anyone any thoughts regarding how a newer speaker such as Fritz or Salk would compare to the ETs?  (my room is 20X14) And does anyone have any experience with the PSB stratus golds and would they be a good fit for the quicksilvers - they are rated 88db/4ohms.  Have a great weekend.
Hi majorc, 
In an earlier post you mentioned the Goldmund Dialogue speakers that impressed with their sound quality. These are 96 db sensitivity and reputed to have a fairly easily driven speaker load.  Are these speakers available to you used? Your QS amplifiers would coast driving these speakers. In your price range take a look at the Tekton Audio Perfect SET speakers. Very efficient and easy to drive.  Another option is the Canadian  Coherent Audio speakers made in Toronto.
