After being laid off in 2009, I literally had no choice but to sell off my entire audio collection of vacuum tube and solid state components I've accumulated since the mid '80s (from Carver and McIntosh to Magnepan to Triangle). While going through a debt management program to pay off my credit cards, I eventually saved up and bought my brother's 1978 Sansui G-7000 Pure Power DC Stereo Receiver, his Klipsch Reference Series RF-10 3-Way Tower Loudspeakers and his used Sony PlayStation 3 for Blu-ray and compact disc playback. That system actually served me extremely well for many years.
In 2019 my debt was finally paid in full, and I managed to save some money and slowly build up my current audio system to what it is today, and it's a far cry power-wise from my venerable 6.5Wpc single-ended 300B triode setup! I finally caught up to 21st century standards with Class D amplification and Hi-Res digital streaming components.
I do miss vacuum tube warmth...maybe someday in the not-too-distance future I may opt for tube preamplification. But at present this 2-channel audio system is incredibly dynamic, transparent, airy and highly detailed without any stringent imperfections associated with earlier Class D switching artifacts. And with the addition of a stand-alone audiophile DAC, compressed streaming music on TuneIn, along with lossless albums on Amazon Music HD have opened up considerably. Eventually I may save up for a new turntable for my vinyl collection...hell, I'd even love a refurbished Nakamichi cassette deck again for my vast collection of tapes I recorded back in the '80s and '90s!
In the meantime, playing with loudspeaker and subwoofer placement has yielded rather amazing results. Tighter bass without one-note boom is noticeable after positioning them closer to the corners (and making small level adjustments), while pulling out the standmount Sonus fabers an inch or two brought out their imaging to even more realistic levels!
Thank you for your comment. Yes, it's a bare concrete floor (I pulled out the original carpeting years ago and just haven't bothered to put down new flooring)...and although I don't doubt other types of footers may work better, the floor is surprisingly level, plus I don't notice any adverse affects using the spikes.
